1 00:00:42,570 --> 00:00:40,590 it had been a great flight with a great 2 00:00:44,310 --> 00:00:42,580 entry in landing and the team was 3 00:00:47,220 --> 00:00:44,320 preparing to handover the vehicle to the 4 00:00:48,810 --> 00:00:47,230 KSC ground folks one of last orders of 5 00:00:50,700 --> 00:00:48,820 business in this process is to 6 00:00:53,640 --> 00:00:50,710 transition from internal vehicle cooling 7 00:00:55,080 --> 00:00:53,650 to ground cooling now in orbit cooling 8 00:00:56,880 --> 00:00:55,090 is accomplished through a combination of 9 00:00:59,850 --> 00:00:56,890 the radiators and flash evaporator 10 00:01:01,530 --> 00:00:59,860 system as shuttle equipment heats up the 11 00:01:03,060 --> 00:01:01,540 freon loops and water loops carry this 12 00:01:06,000 --> 00:01:03,070 heat to the flash evaporator and 13 00:01:08,100 --> 00:01:06,010 radiators to be dispersed into space for 14 00:01:10,530 --> 00:01:08,110 entry the radiators are cold soaked and 15 00:01:12,840 --> 00:01:10,540 then bypassed so that that cooling can 16 00:01:15,210 --> 00:01:12,850 be used on the ground then post landing 17 00:01:17,130 --> 00:01:15,220 the shuttle uses its cold soaked 18 00:01:18,960 --> 00:01:17,140 radiators for a few minutes and then as 19 00:01:20,999 --> 00:01:18,970 they heat up the team activates the 20 00:01:22,850 --> 00:01:21,009 ammonia system which flashes ammonia 21 00:01:25,469 --> 00:01:22,860 onto the freon loops to provide cooling 22 00:01:27,359 --> 00:01:25,479 in order to have a safe transition to 23 00:01:29,310 --> 00:01:27,369 ground cooling the ammonia system has to 24 00:01:31,770 --> 00:01:29,320 be deactivated and confirmed to have no 25 00:01:33,450 --> 00:01:31,780 leaks and then a go is given so the 26 00:01:35,490 --> 00:01:33,460 ground team can activate ground cooling 27 00:01:38,100 --> 00:01:35,500 at least that's the way it's supposed to 28 00:01:40,650 --> 00:01:38,110 go now there are some critical elements 29 00:01:42,029 --> 00:01:40,660 to consider regarding cooling obviously 30 00:01:44,160 --> 00:01:42,039 you have to keep cooling going so 31 00:01:46,109 --> 00:01:44,170 nothing overheats but at the same time 32 00:01:48,090 --> 00:01:46,119 you can't get too cold or you could 33 00:01:50,340 --> 00:01:48,100 freeze the interchange the interchange 34 00:01:52,469 --> 00:01:50,350 er is the heat exchanger where the water 35 00:01:54,930 --> 00:01:52,479 loops dump the cabin heat onto the fan 36 00:01:57,180 --> 00:01:54,940 loops all the shuttle cooling loops meet 37 00:01:59,010 --> 00:01:57,190 there and since we're dealing with water 38 00:02:00,809 --> 00:01:59,020 we can't let it get below 32 degrees 39 00:02:03,090 --> 00:02:00,819 Fahrenheit or the water loops could 40 00:02:05,490 --> 00:02:03,100 freeze and as you know when water 41 00:02:06,840 --> 00:02:05,500 freezes it expands and cracked 42 00:02:08,400 --> 00:02:06,850 you've just ruptured a piece of 43 00:02:10,740 --> 00:02:08,410 equipment that could cost over a million 44 00:02:12,270 --> 00:02:10,750 dollars to replace this is a very 45 00:02:14,820 --> 00:02:12,280 efficient heat exchanger so this would 46 00:02:17,070 --> 00:02:14,830 only take a matter of seconds on sts-27 47 00:02:20,210 --> 00:02:17,080 the e-comm team was faced with just this 48 00:02:38,720 --> 00:02:36,470 I was going to see the it's post-landing 49 00:02:40,850 --> 00:02:38,730 and everything's going normally you're 50 00:02:43,760 --> 00:02:40,860 on the ground you've made it right 51 00:02:45,530 --> 00:02:43,770 what could go wrong here the team is 52 00:02:47,330 --> 00:02:45,540 even starting the post-landing tradition 53 00:02:48,710 --> 00:02:47,340 of hanging the plaque in which one of 54 00:02:51,320 --> 00:02:48,720 the flight controllers is honored with 55 00:02:53,780 --> 00:02:51,330 special recognition however not 56 00:02:55,370 --> 00:02:53,790 everything is done handover to ground 57 00:02:57,500 --> 00:02:55,380 cooling hasn't been completed and the 58 00:02:59,570 --> 00:02:57,510 ecomp team is watching ammonia 59 00:03:04,910 --> 00:02:59,580 performance as suddenly the friendly 60 00:03:06,320 --> 00:03:04,920 temperatures start diving so I want you 61 00:03:09,530 --> 00:03:06,330 to tell me first of all we got Queen 62 00:03:11,750 --> 00:03:09,540 Caroline and Chuck dangle for sts-27 I 63 00:03:13,430 --> 00:03:11,760 want you to tell me your positions for 64 00:03:15,860 --> 00:03:13,440 this flight and what the 65 00:03:18,050 --> 00:03:15,870 responsibilities those positions were so 66 00:03:20,180 --> 00:03:18,060 start with the leader chuck of the team 67 00:03:23,750 --> 00:03:20,190 okay so it's been a while but I think it 68 00:03:25,250 --> 00:03:23,760 was a son entry in orbit one II come for 69 00:03:27,470 --> 00:03:25,260 the flight so we were responsible for 70 00:03:29,509 --> 00:03:27,480 the life support thermal control and 71 00:03:32,930 --> 00:03:29,519 also at that time the electric power 72 00:03:34,640 --> 00:03:32,940 systems on onboard okay I was the acid 73 00:03:37,190 --> 00:03:34,650 entry thermal specifically responsible 74 00:03:38,990 --> 00:03:37,200 for the active cooling and passive 75 00:03:56,990 --> 00:03:39,000 cooling systems on the shuttle including 76 00:04:02,340 --> 00:03:59,250 okay so what were you looking at there 77 00:04:03,990 --> 00:04:02,350 that cued you into the fact hey I got a 78 00:04:05,430 --> 00:04:04,000 problem going on here was that that bill 79 00:04:07,770 --> 00:04:05,440 that went off the alarm that went off 80 00:04:09,840 --> 00:04:07,780 earlier probably actually what happened 81 00:04:12,000 --> 00:04:09,850 was the first thing I saw was we have an 82 00:04:14,760 --> 00:04:12,010 indication on the ammonia system the 83 00:04:16,530 --> 00:04:14,770 primary controller if something goes 84 00:04:18,420 --> 00:04:16,540 along with the logic or goes under temp 85 00:04:20,970 --> 00:04:18,430 it automatically switches to the 86 00:04:22,170 --> 00:04:20,980 secondary controller trying to go to a 87 00:04:24,510 --> 00:04:22,180 different controller to control the 88 00:04:26,970 --> 00:04:24,520 system yet that was the first insight as 89 00:04:29,640 --> 00:04:26,980 I saw is this indication that we just 90 00:04:31,770 --> 00:04:29,650 switched from the primary controller to 91 00:04:33,690 --> 00:04:31,780 the secondary controller and generally 92 00:04:35,490 --> 00:04:33,700 means under tempo that is the only 93 00:04:37,170 --> 00:04:35,500 indication at the time was seeing a 94 00:04:39,210 --> 00:04:37,180 switch and having said that though it's 95 00:04:41,400 --> 00:04:39,220 upstream and we have a power T boosters 96 00:04:43,680 --> 00:04:41,410 so the temperatures hadn't arrived at 97 00:04:50,820 --> 00:04:43,690 yeah how many seconds is that from 98 00:04:54,390 --> 00:04:50,830 ammonia I forgot yeah it's about 45 99 00:04:56,040 --> 00:04:54,400 seconds or so yeah so you guys knew 100 00:04:57,720 --> 00:04:56,050 something something switched over but 101 00:04:59,970 --> 00:04:57,730 you probably didn't have an idea at that 102 00:05:03,780 --> 00:04:59,980 point it was an under tamp right okay 103 00:05:06,180 --> 00:05:03,790 okay and I think he may have just called 104 00:05:24,300 --> 00:05:06,190 hey I think he called it under Tim 105 00:05:29,320 --> 00:05:26,830 now the team has confirmed there's an 106 00:05:30,999 --> 00:05:29,330 under tint problem the cold slug has now 107 00:05:32,980 --> 00:05:31,009 shown up on the downstream temperature 108 00:05:34,629 --> 00:05:32,990 dosers and the extra cold freon is 109 00:05:35,800 --> 00:05:34,639 racing towards the inner changer which 110 00:05:38,170 --> 00:05:35,810 could crack a face with these 111 00:05:40,600 --> 00:05:38,180 temperatures how long does the team have 112 00:05:43,900 --> 00:05:40,610 to respond what is the correct course of 113 00:05:46,480 --> 00:05:43,910 action to take okay so at this point you 114 00:05:50,559 --> 00:05:46,490 know that you've got the about too low 115 00:05:52,270 --> 00:05:50,569 and what are you thinking one of my 116 00:05:57,339 --> 00:05:52,280 thing at the time there was a hairy edge 117 00:05:58,749 --> 00:05:57,349 where you know as the I knew that it may 118 00:06:00,870 --> 00:05:58,759 be the initiated ground : there's some 119 00:06:03,790 --> 00:06:00,880 spec leakage to the ammonia boiler that 120 00:06:07,570 --> 00:06:03,800 it leaks ammonia so you're getting some 121 00:06:09,040 --> 00:06:07,580 cooling from it whether it's on or when 122 00:06:10,779 --> 00:06:09,050 it's on no matter what if it's not 123 00:06:11,680 --> 00:06:10,789 required on it so it's providing extra 124 00:06:14,980 --> 00:06:11,690 cooling to loop 125 00:06:17,800 --> 00:06:14,990 initial thought was okay we're down just 126 00:06:21,070 --> 00:06:17,810 broke 32 degrees maybe they're cool and 127 00:06:21,580 --> 00:06:21,080 they're cooling cards just to go low am 128 00:06:23,560 --> 00:06:21,590 i right now 129 00:06:24,999 --> 00:06:23,570 ready to take this drastic action yet or 130 00:06:26,920 --> 00:06:25,009 is this maybe we can take the ammonia 131 00:06:28,990 --> 00:06:26,930 boiler off and that would be sufficient 132 00:06:31,899 --> 00:06:29,000 to bring it above freezing again what's 133 00:06:33,459 --> 00:06:31,909 my initial thoughts it was not it was 134 00:06:35,800 --> 00:06:33,469 pretty getting pretty excited you can 135 00:06:38,620 --> 00:06:35,810 hear was the fact that you know we were 136 00:06:40,810 --> 00:06:38,630 actually below the freezing point of the 137 00:06:41,529 --> 00:06:40,820 water and we needed to do something 138 00:06:43,300 --> 00:06:41,539 quick 139 00:06:44,860 --> 00:06:43,310 so that was an initial reaction let's 140 00:06:47,020 --> 00:06:44,870 get it off and see if that won't bring 141 00:06:49,300 --> 00:06:47,030 it to the trip back up above freezing so 142 00:06:51,520 --> 00:06:49,310 what's what is the issue here with 143 00:06:56,680 --> 00:06:51,530 getting too cold what's the what's the 144 00:06:58,809 --> 00:06:56,690 problem with doing that the interchange 145 00:07:01,510 --> 00:06:58,819 is a very efficient heat exchanger and 146 00:07:04,600 --> 00:07:01,520 it's got freon on one side and water on 147 00:07:07,330 --> 00:07:04,610 the other and if you put in freon below 148 00:07:09,879 --> 00:07:07,340 32 degrees in pretty short order you're 149 00:07:12,790 --> 00:07:09,889 going to end up freezing water turn the 150 00:07:15,129 --> 00:07:12,800 water into ice it expands and volume 151 00:07:17,200 --> 00:07:15,139 change in heat exchanger can break 152 00:07:19,779 --> 00:07:17,210 that'd be pretty expensive to try to 153 00:07:21,129 --> 00:07:19,789 replace that and one of the big things 154 00:07:23,649 --> 00:07:21,139 was that we have done that before and 155 00:07:26,800 --> 00:07:23,659 sts-3 it was a better place the big 156 00:07:29,080 --> 00:07:26,810 thing is I don't think they have any 157 00:07:31,360 --> 00:07:29,090 spares and I think the big thing is it 158 00:07:32,950 --> 00:07:31,370 just bits of not only the cost which 159 00:07:35,379 --> 00:07:32,960 they estimated 100 million dollars but 160 00:07:37,450 --> 00:07:35,389 getting a new one in installing it from 161 00:07:39,309 --> 00:07:37,460 the downtown of the vehicle was a big 162 00:07:40,899 --> 00:07:39,319 impact impact of schedule would have 163 00:07:42,700 --> 00:07:40,909 been pretty enormous right I mean 164 00:07:46,959 --> 00:07:42,710 basically can't power how vehicle what 165 00:07:50,019 --> 00:07:46,969 the real move or loosen on actors so 166 00:07:51,550 --> 00:07:50,029 knowing that why didn't she just go take 167 00:07:53,110 --> 00:07:51,560 the drastic it what is drastic about 168 00:07:54,399 --> 00:07:53,120 turning the friendly soft ones just say 169 00:07:56,350 --> 00:07:54,409 let's go ahead and turn them off what's 170 00:07:57,670 --> 00:07:56,360 what's the issue there you know so we 171 00:07:59,679 --> 00:07:57,680 got on one side we don't want to freeze 172 00:08:00,700 --> 00:07:59,689 the interchange er why don't we want to 173 00:08:09,129 --> 00:08:00,710 just turn the family piece off what's 174 00:08:10,920 --> 00:08:09,139 the issue there well I kind of had my 175 00:08:13,480 --> 00:08:10,930 way of saying who gets below 30 degrees 176 00:08:16,390 --> 00:08:13,490 that's what my land my saying we're not 177 00:08:18,369 --> 00:08:16,400 playing anymore and he's you're gonna 178 00:08:20,890 --> 00:08:18,379 hearing a little bit it happened quickly 179 00:08:23,980 --> 00:08:20,900 from drop down and it was very officer 180 00:08:25,390 --> 00:08:23,990 obvious that once it got to obstacle low 181 00:08:26,829 --> 00:08:25,400 of the deucer which was twenty four 182 00:08:30,939 --> 00:08:26,839 point nine you'll hear that several 183 00:08:36,670 --> 00:08:30,949 times repeated very obvious what we need 184 00:08:39,069 --> 00:08:36,680 to do but it was to me was a drastic I 185 00:08:51,600 --> 00:08:39,079 mean the fact that we potentially shut 186 00:08:51,610 --> 00:09:50,970 that's okay so basically you're okay 187 00:09:55,449 --> 00:09:53,259 sounds like nothing you made the call 188 00:09:58,809 --> 00:09:55,459 for the frame loops nothing happened 189 00:10:01,840 --> 00:09:58,819 right initially and and I'm still like 190 00:10:04,960 --> 00:10:01,850 they're you know they're actually the 191 00:10:06,670 --> 00:10:04,970 trawl team was basically and like I said 192 00:10:11,889 --> 00:10:06,680 the post mission mode where they're 193 00:10:13,960 --> 00:10:11,899 doing the post black hanging and stuff 194 00:10:16,720 --> 00:10:13,970 and I think even GC got to the point or 195 00:10:18,759 --> 00:10:16,730 actually we temporarily they shut down 196 00:10:21,100 --> 00:10:18,769 calm between the vehicles what I heard 197 00:10:23,380 --> 00:10:21,110 later for the infirm their first initial 198 00:10:25,240 --> 00:10:23,390 call to the vehicle to turn off both 199 00:10:26,500 --> 00:10:25,250 trailers and I don't think that we left 200 00:10:29,230 --> 00:10:26,510 the house they're probably thinking the 201 00:10:31,809 --> 00:10:29,240 rule the one point one hey the crews 202 00:10:32,710 --> 00:10:31,819 gone why should I keep calm up I mean 203 00:10:34,930 --> 00:10:32,720 we're already doing the plaque hanging 204 00:10:38,230 --> 00:10:34,940 right let's just let's just shut this 205 00:10:39,880 --> 00:10:38,240 thing down so okay I don't know what I 206 00:10:44,019 --> 00:10:39,890 don't know what all the factors were in 207 00:10:50,060 --> 00:10:44,029 that listening to that recording which I 208 00:10:55,010 --> 00:10:52,460 just being kind of stepping back as an 209 00:10:56,870 --> 00:10:55,020 observer to myself if I would have had 210 00:10:59,870 --> 00:10:56,880 the wherewithal I think it would have 211 00:11:01,790 --> 00:10:59,880 helped to be more exact in the call 212 00:11:03,920 --> 00:11:01,800 especially knowing that the flight crew 213 00:11:05,780 --> 00:11:03,930 was not in there 214 00:11:08,500 --> 00:11:05,790 who probably could have responded very 215 00:11:11,060 --> 00:11:08,510 well to be activate both freon loops 216 00:11:14,090 --> 00:11:11,070 were the support person in there instead 217 00:11:18,290 --> 00:11:14,100 a more precise call like on panel l1 218 00:11:21,410 --> 00:11:18,300 freon pump one off loop - I think that 219 00:11:26,390 --> 00:11:21,420 in hindsight would have helped get that 220 00:11:28,400 --> 00:11:26,400 done much faster if I was a ASP in the 221 00:11:30,560 --> 00:11:28,410 cockpit trying to interpret that call I 222 00:11:35,740 --> 00:11:30,570 probably have trouble myself right here 223 00:11:37,850 --> 00:11:35,750 ms Wanda had seemed in a year where 224 00:11:57,230 --> 00:11:37,860 that's good that's a very good point 225 00:11:58,640 --> 00:11:57,240 that's a good point okay so what was 226 00:12:00,140 --> 00:11:58,650 going on there I made the call for the 227 00:12:02,810 --> 00:12:00,150 Fran loops and now Quinn's calling again 228 00:12:06,350 --> 00:12:02,820 let's get one off yeah so I can tell you 229 00:12:08,510 --> 00:12:06,360 from my perspective I was trying to find 230 00:12:10,670 --> 00:12:08,520 the procedure for a VAT Bell tell about 231 00:12:13,490 --> 00:12:10,680 temple oh I think in the entry checklist 232 00:12:16,460 --> 00:12:13,500 right okay so I was thumbing through the 233 00:12:21,770 --> 00:12:16,470 book to fly to to try and find that 234 00:12:24,170 --> 00:12:21,780 procedure to save myself so I after 235 00:12:27,410 --> 00:12:24,180 making the call to turn both freon loops 236 00:12:29,990 --> 00:12:27,420 off I think I was under the assumption 237 00:12:31,580 --> 00:12:30,000 that that would happen quickly I'm going 238 00:12:36,230 --> 00:12:31,590 to find the procedure to look for 239 00:12:38,480 --> 00:12:36,240 subsequent steps to guide us and so 240 00:12:41,600 --> 00:12:38,490 Quinn called and I'm asking questions I 241 00:12:46,310 --> 00:12:41,610 think out of that procedure and Quinn 242 00:12:47,270 --> 00:12:46,320 says hey I just please turn off it hit 243 00:12:50,780 --> 00:12:47,280 me at that point 244 00:12:52,580 --> 00:12:50,790 oh they didn't respond to the call right 245 00:12:54,560 --> 00:12:52,590 and you Quinn can't see each other here 246 00:12:57,680 --> 00:12:54,570 right ones in one room ones in the other 247 00:13:00,050 --> 00:12:57,690 room so and sometimes there's over the 248 00:13:01,550 --> 00:13:00,060 airwave conversation that goes on and so 249 00:13:02,040 --> 00:13:01,560 you didn't know why they weren't turning 250 00:13:04,739 --> 00:13:02,050 the friendly 251 00:13:06,419 --> 00:13:04,749 right and I'd take from the is a mid 252 00:13:08,249 --> 00:13:06,429 perspective one thing that really taught 253 00:13:08,850 --> 00:13:08,259 me it was okay I've already made the 254 00:13:12,299 --> 00:13:08,860 call 255 00:13:14,369 --> 00:13:12,309 I'm watching Chuck Chuck is watching 256 00:13:17,340 --> 00:13:14,379 this data to don't need a bother he sees 257 00:13:23,009 --> 00:13:17,350 what's happening I'm kind of in the 258 00:13:25,889 --> 00:13:23,019 background dancing panicking but I am 259 00:13:27,900 --> 00:13:25,899 NOT I learned after the fact that when 260 00:13:31,109 --> 00:13:27,910 he started talking about what I want to 261 00:13:32,549 --> 00:13:31,119 do next it was a fear through fear 262 00:13:33,840 --> 00:13:32,559 through mean that he doesn't realize 263 00:13:37,019 --> 00:13:33,850 they're still not off yet 264 00:13:39,780 --> 00:13:37,029 and then I'm questioning why didn't they 265 00:13:43,169 --> 00:13:39,790 go off why didn't they they actually do 266 00:13:44,999 --> 00:13:43,179 it so but the point in listening for 267 00:13:48,210 --> 00:13:45,009 future guys is you know don't make an 268 00:13:49,739 --> 00:13:48,220 assumption you're free clickers look in 269 00:13:51,269 --> 00:13:49,749 the data this is all växjö it's 270 00:13:54,840 --> 00:13:51,279 happening much quicker than it really is 271 00:13:57,269 --> 00:13:54,850 but we had I want to say correct me from 272 00:13:59,579 --> 00:13:57,279 long 60 to 90 seconds somewhere before 273 00:14:02,220 --> 00:13:59,589 we would have damaged the interchanges 274 00:14:05,359 --> 00:14:02,230 so the 45 have about 10 or changes 275 00:14:08,879 --> 00:14:05,369 another 45 and we're ticking along it's 276 00:14:13,230 --> 00:14:08,889 20 seconds 30 seconds and I should have 277 00:14:15,239 --> 00:14:13,240 been going hey Chuck I should have been 278 00:14:16,739 --> 00:14:15,249 more proactive I made the assumption 279 00:14:18,629 --> 00:14:16,749 that he's looking the data he's singing 280 00:14:20,789 --> 00:14:18,639 it - he's congressman put the fear of 281 00:14:22,410 --> 00:14:20,799 God what do you realize he'd made a call 282 00:14:24,569 --> 00:14:22,420 like what we're gonna do next and I'm 283 00:14:26,449 --> 00:14:24,579 realizing he's not looking at the data 284 00:14:28,949 --> 00:14:26,459 and I'm realizing I should have been 285 00:14:30,780 --> 00:14:28,959 pushing it well I certainly should have 286 00:14:33,509 --> 00:14:30,790 been paying attention to get the primary 287 00:14:35,039 --> 00:14:33,519 action to ensure that it was done yeah 288 00:14:37,799 --> 00:14:35,049 and so that was one of the things that I 289 00:14:39,960 --> 00:14:37,809 wish I had done better back at the time 290 00:14:42,179 --> 00:14:39,970 was to be more cognizant to making sure 291 00:14:44,129 --> 00:14:42,189 that they took the action that we asked 292 00:14:46,559 --> 00:14:44,139 I'm just taking too much it was my job 293 00:14:48,230 --> 00:14:46,569 to watch the systems I should keep them 294 00:14:50,280 --> 00:14:48,240 Kevin it's a team effort both ways 295 00:14:52,289 --> 00:14:50,290 absolutely team effort all the way all 296 00:14:52,759 --> 00:14:52,299 the way around good and bad we work as a 297 00:15:09,680 --> 00:14:52,769 team 298 00:15:13,560 --> 00:15:11,550 sound like he's getting little stressed 299 00:15:15,750 --> 00:15:13,570 out there yeah I think the seriousness 300 00:15:18,030 --> 00:15:15,760 of it was probably starting to soak in 301 00:15:19,530 --> 00:15:18,040 yeah you probably I'm just guessing you 302 00:15:20,820 --> 00:15:19,540 just realized I made a call and I'm 303 00:15:24,150 --> 00:15:20,830 looking at the procedures and my call 304 00:15:25,890 --> 00:15:24,160 didn't go go up and number less and I 305 00:15:26,310 --> 00:15:25,900 need to push this thing go harder yes 306 00:15:30,000 --> 00:15:26,320 yeah 307 00:15:31,860 --> 00:15:30,010 the lesson to be learned there was give 308 00:15:33,750 --> 00:15:31,870 a more exact call yeah and you're more 309 00:15:35,490 --> 00:15:33,760 likely to get a quick response so for 310 00:15:37,170 --> 00:15:35,500 you to call it because like you said 311 00:15:40,200 --> 00:15:37,180 there was no panel there it's just the 312 00:15:58,680 --> 00:15:40,210 pumps and if it was an ASP they might be 313 00:16:00,990 --> 00:15:58,690 looking he's looking yeah okay the free 314 00:16:02,190 --> 00:16:01,000 loops are off the cold slug is stopped 315 00:16:05,190 --> 00:16:02,200 but it's still sitting there 316 00:16:07,320 --> 00:16:05,200 a silent menace ready to wreak havoc the 317 00:16:09,060 --> 00:16:07,330 team knows this but how does the team 318 00:16:11,519 --> 00:16:09,070 keep the interchange from cracking and 319 00:16:14,280 --> 00:16:11,529 still reestablish cooling now how much 320 00:16:15,540 --> 00:16:14,290 time do they have so you got both frame 321 00:16:18,840 --> 00:16:15,550 loops off and you know that's a drastic 322 00:16:21,840 --> 00:16:18,850 action how long could the frame looks be 323 00:16:23,310 --> 00:16:21,850 off and that you know and how do you 324 00:16:25,500 --> 00:16:23,320 gauge sex it's a big deal to have in the 325 00:16:27,269 --> 00:16:25,510 frame lips off did you are you starting 326 00:16:29,490 --> 00:16:27,279 another timer because you were starting 327 00:16:31,199 --> 00:16:29,500 your your interchange your fries timer 328 00:16:32,850 --> 00:16:31,209 it's like I know I got so much time 329 00:16:35,220 --> 00:16:32,860 before that cold slug hits now turn the 330 00:16:39,600 --> 00:16:35,230 feelings off you got another timer going 331 00:16:42,600 --> 00:16:39,610 now I didn't have a ton I didn't have a 332 00:16:45,329 --> 00:16:42,610 timer guy I had the the the general 333 00:16:48,390 --> 00:16:45,339 knowledge that things don't melt down 334 00:16:52,699 --> 00:16:48,400 instantly right to me probably the fuel 335 00:16:54,960 --> 00:16:52,709 cells or of the biggest concern and I 336 00:16:56,610 --> 00:16:54,970 know that you know for fuel cells what 337 00:16:58,410 --> 00:16:56,620 we could go for loss of coolant pumps 338 00:17:01,769 --> 00:16:58,420 don't feel so we could go like nine 339 00:17:05,490 --> 00:17:01,779 minutes or thereabouts so yeah I think 340 00:17:07,439 --> 00:17:05,500 you have probably at least that order of 341 00:17:09,030 --> 00:17:07,449 magnitude before something you know 342 00:17:13,170 --> 00:17:09,040 catastrophic 343 00:17:14,880 --> 00:17:13,180 so clearly I think you have not a lot of 344 00:17:17,070 --> 00:17:14,890 time but an order of magnitude more time 345 00:17:19,260 --> 00:17:17,080 to deal with them being off than to deal 346 00:17:21,510 --> 00:17:19,270 with the cold slug coming around right 347 00:17:24,570 --> 00:17:21,520 okay that kind of what did you have a 348 00:17:27,750 --> 00:17:24,580 clock going in your mind at all well the 349 00:17:28,920 --> 00:17:27,760 good thing is we had the EPS guys and 350 00:17:31,200 --> 00:17:28,930 the fuel cells that I knew was the 351 00:17:33,900 --> 00:17:31,210 shortfall we had the EPS guy washing the 352 00:17:35,640 --> 00:17:33,910 fuel cells across there and he would be 353 00:17:39,180 --> 00:17:35,650 the one to make the recommendation 354 00:17:41,310 --> 00:17:39,190 whether we had to terminate the merge do 355 00:17:45,930 --> 00:17:41,320 it and basically a power down of the 356 00:17:48,150 --> 00:17:45,940 vehicle we couldn't gain it so now let 357 00:17:53,450 --> 00:17:48,160 me ask you this have you guys seemed to 358 00:17:57,420 --> 00:17:53,460 this case basically prior to this no I 359 00:17:58,890 --> 00:17:57,430 don't remember no not really and the 360 00:18:02,390 --> 00:17:58,900 other thing even when they did start 361 00:18:06,750 --> 00:18:02,400 simulating this doing it a 362 00:18:09,780 --> 00:18:06,760 simms of this later after this event for 363 00:18:12,480 --> 00:18:09,790 future teams it one of the things about 364 00:18:15,780 --> 00:18:12,490 the post line was always very stressful 365 00:18:19,200 --> 00:18:15,790 for me is you can't recreate in training 366 00:18:20,730 --> 00:18:19,210 the all the noises the ground convoy is 367 00:18:23,580 --> 00:18:20,740 the confusion of the additional loops 368 00:18:26,430 --> 00:18:23,590 the communication that's going all loops 369 00:18:28,290 --> 00:18:26,440 your lives and listening to it was very 370 00:18:30,000 --> 00:18:28,300 noisy it was always a very stressful 371 00:18:31,830 --> 00:18:30,010 time for me when I became an e comment 372 00:18:34,590 --> 00:18:31,840 what asset entry was because we didn't 373 00:18:36,570 --> 00:18:34,600 train it and they were just not only 374 00:18:38,520 --> 00:18:36,580 that even even afterwards was this the 375 00:18:40,320 --> 00:18:38,530 chaos they everyone who's getting done 376 00:18:41,940 --> 00:18:40,330 with her job in the control center it 377 00:18:43,980 --> 00:18:41,950 was noisy in the control center it was 378 00:18:45,930 --> 00:18:43,990 noisy on the loops and he had this 379 00:18:48,750 --> 00:18:45,940 unknown factor what we don't train with 380 00:18:51,450 --> 00:18:48,760 which is the KSC guys very often that we 381 00:18:54,660 --> 00:18:51,460 we did start using direct comm with the 382 00:18:56,550 --> 00:18:54,670 guys trying to minimize any kind of 383 00:18:59,640 --> 00:18:56,560 problems we can directly talk to the 384 00:19:01,920 --> 00:18:59,650 guys at the convoy but no it was the 385 00:19:04,290 --> 00:19:01,930 training was we sat now I walked through 386 00:19:06,120 --> 00:19:04,300 this procedure there was also a lot of 387 00:19:08,220 --> 00:19:06,130 lessons learned like I said from sts-3 388 00:19:09,480 --> 00:19:08,230 with things that they had done after we 389 00:19:12,330 --> 00:19:09,490 handed over they did some additional 390 00:19:13,590 --> 00:19:12,340 ammonia boiler tests that they under Tim 391 00:19:15,240 --> 00:19:13,600 and there were some lesson learned from 392 00:19:17,850 --> 00:19:15,250 that and the fact that that happened 393 00:19:20,660 --> 00:19:17,860 there made it very cognizant 394 00:19:22,799 --> 00:19:20,670 what happened once it could happen again 395 00:19:27,630 --> 00:19:22,809 yeah I think I just can't emphasize 396 00:19:30,289 --> 00:19:27,640 enough the few minutes of time that we 397 00:19:35,520 --> 00:19:30,299 took preparing and walking through that 398 00:19:37,950 --> 00:19:35,530 was just enormous hell I think it's as 399 00:19:40,260 --> 00:19:37,960 much better is as I could have done in 400 00:19:43,650 --> 00:19:40,270 that situation and I and I certainly 401 00:19:48,000 --> 00:19:43,660 wish that I had I think I could have 402 00:19:49,980 --> 00:19:48,010 done a lot worse had we not done that 403 00:19:56,100 --> 00:19:49,990 preparation because turning off of freon 404 00:20:00,150 --> 00:19:56,110 loops is a you want to do what yeah the 405 00:20:02,789 --> 00:20:00,160 fact that we had talked through it it at 406 00:20:05,070 --> 00:20:02,799 least it resonated with me that yeah 407 00:20:07,440 --> 00:20:05,080 that's what we have to do we talked 408 00:20:11,010 --> 00:20:07,450 through that we talked about the the 409 00:20:13,440 --> 00:20:11,020 urgency of time and how that has to be 410 00:20:17,280 --> 00:20:13,450 done to preserve that heat exchangers so 411 00:20:20,159 --> 00:20:17,290 that I at least never questioned that 412 00:20:24,990 --> 00:20:20,169 aspect of it had we not talked through 413 00:20:27,750 --> 00:20:25,000 that case is is deeper respect as I have 414 00:20:31,500 --> 00:20:27,760 for Quinn and knew that he was I had the 415 00:20:34,650 --> 00:20:31,510 best thermal guy in in the back room I 416 00:20:38,700 --> 00:20:34,660 don't think I would have just said okay 417 00:20:41,669 --> 00:20:38,710 whatever you say I think I would have at 418 00:20:43,409 --> 00:20:41,679 least questioned some and that might 419 00:20:47,340 --> 00:20:43,419 have made the difference in the case so 420 00:20:48,990 --> 00:20:47,350 so that preparation we we did was just 421 00:20:51,510 --> 00:20:49,000 worth invaluable 422 00:20:53,430 --> 00:20:51,520 now was that SOP for you like if you had 423 00:20:55,799 --> 00:20:53,440 an event coming up that you would talk 424 00:20:57,030 --> 00:20:55,809 to the backroom say this is the things 425 00:20:59,669 --> 00:20:57,040 that could go wrong this is what we're 426 00:21:01,080 --> 00:20:59,679 gonna do was that just SOP or what you 427 00:21:04,890 --> 00:21:01,090 just kind of got lucky that time that 428 00:21:07,380 --> 00:21:04,900 you did that you know I don't know it's 429 00:21:09,930 --> 00:21:07,390 probably SOP when you feel like you 430 00:21:13,500 --> 00:21:09,940 don't know as much as you should know 431 00:21:14,640 --> 00:21:13,510 about something and and again coming 432 00:21:16,260 --> 00:21:14,650 from the electrical side of the house 433 00:21:20,039 --> 00:21:16,270 and trying to pick up the thermal and 434 00:21:22,530 --> 00:21:20,049 life-support stuff you you don't pick up 435 00:21:24,900 --> 00:21:22,540 all the knowledge you need in a matter 436 00:21:27,440 --> 00:21:24,910 of a couple of years which is probably 437 00:21:30,980 --> 00:21:27,450 as long as I had been thinking about it 438 00:21:35,269 --> 00:21:30,990 so it's many years of a preparation to 439 00:21:38,299 --> 00:21:35,279 really understand those systems so to me 440 00:21:40,970 --> 00:21:38,309 it was basically all that we could all 441 00:21:44,440 --> 00:21:40,980 that I could do personally in limited 442 00:21:49,190 --> 00:21:44,450 time in order to be the most prepared 443 00:21:50,419 --> 00:21:49,200 that I could so had I had five or ten 444 00:21:52,639 --> 00:21:50,429 years experience and then I might have 445 00:21:54,409 --> 00:21:52,649 been more complacent to not felt the 446 00:21:58,549 --> 00:21:54,419 need to do that but I did it out of a 447 00:22:01,909 --> 00:21:58,559 personal I have to cover myself right 448 00:22:03,230 --> 00:22:01,919 right gotcha excellent let's keep going 449 00:22:21,470 --> 00:22:03,240 here so we got that right now the free 450 00:22:23,289 --> 00:22:21,480 loops are that's something 451 00:22:26,180 --> 00:22:23,299 sounds like we you talked about this 452 00:22:28,250 --> 00:22:26,190 previously so had you already stepped to 453 00:22:32,810 --> 00:22:28,260 kind of through the recovery of yes 454 00:22:34,610 --> 00:22:32,820 actually over time for him we actually 455 00:22:36,889 --> 00:22:34,620 went through all the continued CG 456 00:22:39,950 --> 00:22:36,899 aspects or recovery steps and kind of 457 00:22:41,450 --> 00:22:39,960 walking through it was really uh so we 458 00:22:54,639 --> 00:22:41,460 kind of do the plan that we're going to 459 00:23:00,440 --> 00:22:57,379 remember where those steps in the Indian 460 00:23:04,700 --> 00:23:00,450 trajecsys Tyvek kilo to reactivate like 461 00:23:06,049 --> 00:23:04,710 that yes okay that's good and so your 462 00:23:07,519 --> 00:23:06,059 sounds like you're doing one loop at a 463 00:23:10,190 --> 00:23:07,529 time why don't you just turn them you 464 00:23:11,360 --> 00:23:10,200 know the under temps we've stopped it 465 00:23:13,310 --> 00:23:11,370 let's go and turn them both on why did 466 00:23:15,200 --> 00:23:13,320 you do it that way instead of one loop 467 00:23:16,610 --> 00:23:15,210 at a time oh it was actually part of a 468 00:23:18,889 --> 00:23:16,620 procedure but the real reason is is 469 00:23:23,330 --> 00:23:18,899 you're owing your you're only activating 470 00:23:25,529 --> 00:23:23,340 one so half the ones saying you're only 471 00:23:27,479 --> 00:23:25,539 doing with half the coleslaw at a time 472 00:23:29,399 --> 00:23:27,489 and the vehicles being hot right now 473 00:23:30,719 --> 00:23:29,409 water loops we've got interchanges been 474 00:23:33,149 --> 00:23:30,729 hot since it's been running without any 475 00:23:37,080 --> 00:23:33,159 cooling so we trying to introduce one 476 00:23:39,359 --> 00:23:37,090 loop look it over only add you know and 477 00:23:42,119 --> 00:23:39,369 one of the cold slugs at a time and then 478 00:23:44,700 --> 00:23:42,129 evaluate you know how the system is 479 00:23:46,440 --> 00:23:44,710 working so you get the insight into the 480 00:23:48,749 --> 00:23:46,450 situation whether or not you're under 481 00:23:51,869 --> 00:23:48,759 temp situation is right basically 482 00:23:53,729 --> 00:23:51,879 remedied right or not with with you 483 00:23:55,739 --> 00:23:53,739 could look at as half the risk you know 484 00:23:57,690 --> 00:23:55,749 half the heat rejection right quality 485 00:23:58,979 --> 00:23:57,700 the heat exchanger and I wasn't paying 486 00:24:00,839 --> 00:23:58,989 attention to gel pick where you're 487 00:24:02,519 --> 00:24:00,849 picking the freon loop that was 488 00:24:04,769 --> 00:24:02,529 associated with the ammonia system I 489 00:24:06,539 --> 00:24:04,779 wasn't paying attention to that actually 490 00:24:08,430 --> 00:24:06,549 Baltimore loops were off at the time so 491 00:24:09,839 --> 00:24:08,440 I mean we turn it back oh you knew both 492 00:24:11,969 --> 00:24:09,849 ammonia systems are off it didn't matter 493 00:24:16,080 --> 00:24:11,979 right okay that's right okay do we have 494 00:24:18,239 --> 00:24:16,090 an additional measurement on one yeah 495 00:24:20,789 --> 00:24:18,249 you had an interchange are in on loop 496 00:24:21,960 --> 00:24:20,799 one okay yeah so out of the fit swipe we 497 00:24:22,710 --> 00:24:21,970 might have picked you might have picked 498 00:24:27,930 --> 00:24:22,720 that one first 499 00:24:30,719 --> 00:24:27,940 okay I just did what he says chuckles 500 00:24:32,639 --> 00:24:30,729 good okay now I can tremor now if he 501 00:24:34,409 --> 00:24:32,649 already gone flow proportioning valve to 502 00:24:36,989 --> 00:24:34,419 payload at this point I can't actually 503 00:24:38,879 --> 00:24:36,999 believe it or not the old procedure was 504 00:24:40,379 --> 00:24:38,889 go to interchange er the assumption was 505 00:24:42,839 --> 00:24:40,389 the payload loop was gonna be the so 506 00:24:45,690 --> 00:24:42,849 slower flowing loops so with the 507 00:24:46,560 --> 00:24:45,700 procedures written generically always go 508 00:24:49,859 --> 00:24:46,570 to interchange 509 00:24:51,989 --> 00:24:49,869 oh it's been changed and so right right 510 00:24:54,060 --> 00:24:51,999 right so if you had a payload you would 511 00:25:26,450 --> 00:24:54,070 freeze that payloads water if it was 512 00:25:30,210 --> 00:25:28,800 did I catch that right y'all didn't turn 513 00:25:32,580 --> 00:25:30,220 the water loop off unless they must have 514 00:25:35,010 --> 00:25:32,590 said it wrong you may have said on well 515 00:25:37,140 --> 00:25:35,020 maybe that's on yeah one of the points 516 00:25:40,050 --> 00:25:37,150 to is in when you listen to this loop 517 00:25:41,850 --> 00:25:40,060 it's amazing to me after listening to 518 00:25:44,520 --> 00:25:41,860 this thing how I knew exactly what I'm 519 00:25:53,550 --> 00:25:44,530 going to do but I was under the stress 520 00:25:55,650 --> 00:25:53,560 in panic but under the stress I was 521 00:25:58,890 --> 00:25:55,660 having trying to communicating exactly I 522 00:26:01,290 --> 00:25:58,900 was having trouble between between 1 and 523 00:26:02,850 --> 00:26:01,300 2 and what pump I was filling to 524 00:26:03,780 --> 00:26:02,860 communicate Chuck did an excellent job 525 00:26:05,430 --> 00:26:03,790 it's ok 526 00:26:07,710 --> 00:26:05,440 I heard what you said is this really 527 00:26:09,300 --> 00:26:07,720 what you wanted were you saying and it 528 00:26:11,430 --> 00:26:09,310 was very easy to go back and say yes 529 00:26:14,370 --> 00:26:11,440 that's what I meant to say but it was 530 00:26:15,960 --> 00:26:14,380 amazing how simple things like loop 1 531 00:26:17,460 --> 00:26:15,970 loop 2 even they had the procedure over 532 00:26:19,140 --> 00:26:17,470 I was saying the wrong thing he just 533 00:26:21,150 --> 00:26:19,150 gonna stress it and I think Chuck said 534 00:26:23,100 --> 00:26:21,160 you had you got yourself out of the 535 00:26:24,360 --> 00:26:23,110 quick response situation by turn of the 536 00:26:26,520 --> 00:26:24,370 friend loose off now you had kind of an 537 00:26:27,750 --> 00:26:26,530 order of magnitude more so you could 538 00:26:29,940 --> 00:26:27,760 slow down a little bit right a little 539 00:26:32,730 --> 00:26:29,950 you know yeah not a lot you got the fuel 540 00:26:34,140 --> 00:26:32,740 cells out there heating up but yeah you 541 00:26:35,580 --> 00:26:34,150 could able to slow down a little so does 542 00:26:37,140 --> 00:26:35,590 that go through your mind ok I can take 543 00:26:39,540 --> 00:26:37,150 a little bit more time make sure I'm 544 00:27:08,170 --> 00:26:39,550 understanding the you know pedal to the 545 00:28:32,750 --> 00:27:36,080 okay I never heard that before until you 546 00:28:36,780 --> 00:28:34,920 at that point you had one friend loop up 547 00:28:38,460 --> 00:28:36,790 and I heard the EPSS mentor right when 548 00:28:40,080 --> 00:28:38,470 that Larry men are back there saying the 549 00:28:43,560 --> 00:28:40,090 fuel cell returned temps starting to 550 00:28:45,570 --> 00:28:43,570 skyrocket at that point with one 551 00:28:46,980 --> 00:28:45,580 friendly pup were y'all feeling pretty 552 00:28:50,970 --> 00:28:46,990 good about yourselves or did you need to 553 00:28:53,040 --> 00:28:50,980 keep going get both loops up to you know 554 00:29:03,420 --> 00:28:53,050 get yourself in a really good config or 555 00:29:36,480 --> 00:29:03,430 what was your clock like or starting to 556 00:29:38,070 --> 00:29:36,490 get over the hump so I know you just 557 00:29:40,800 --> 00:29:38,080 said it there but just to put it out 558 00:29:42,090 --> 00:29:40,810 there so at that point what was the 559 00:29:48,540 --> 00:29:42,100 problem and how did this whole thing 560 00:29:51,860 --> 00:29:48,550 kind of evolve they did a new when they 561 00:29:54,870 --> 00:29:51,870 did a new procedure at on the cooling 562 00:29:59,580 --> 00:29:54,880 cart with a research fluid 563 00:30:01,590 --> 00:29:59,590 I believe research recirculated the 564 00:30:06,810 --> 00:30:01,600 fluid in the cooling cart it would allow 565 00:30:08,430 --> 00:30:06,820 this old slug to build up and so when 566 00:30:10,020 --> 00:30:08,440 they initiated they got this really cold 567 00:30:12,420 --> 00:30:10,030 slug to occur and I think that was it 568 00:30:14,490 --> 00:30:12,430 was a but there was a new procedure they 569 00:30:18,390 --> 00:30:14,500 implemented it for 27 and I think they 570 00:30:20,910 --> 00:30:18,400 didn't change it back after 27 571 00:30:24,930 --> 00:30:20,920 although standard procedure they had was 572 00:30:26,490 --> 00:30:24,940 it back then was it standard to have the 573 00:30:27,750 --> 00:30:26,500 ammonia in the ground cooling but at the 574 00:30:29,040 --> 00:30:27,760 same time they both came up at the same 575 00:30:31,170 --> 00:30:29,050 time right he had ammonia and they 576 00:30:33,360 --> 00:30:31,180 hooked up is that was that standard back 577 00:30:35,400 --> 00:30:33,370 then normally they would notify us ahead 578 00:30:37,410 --> 00:30:35,410 of time that they're ready to initiate 579 00:30:39,690 --> 00:30:37,420 at that point we would make the call at 580 00:30:41,160 --> 00:30:39,700 deactivate the ammonia and then they 581 00:30:42,000 --> 00:30:41,170 would initiate in this case they 582 00:30:44,910 --> 00:30:42,010 initiated 583 00:30:46,620 --> 00:30:44,920 I don't know wasn't because it's a new 584 00:30:50,010 --> 00:30:46,630 procedure researched and this Cole 585 00:30:51,210 --> 00:30:50,020 suddenly initiated it up but we were not 586 00:30:53,010 --> 00:30:51,220 notified that they were about to 587 00:30:54,960 --> 00:30:53,020 initiate it and that there was also 588 00:30:56,880 --> 00:30:54,970 there was some pressure that they knew 589 00:30:59,280 --> 00:30:56,890 that we're getting near the end of our 590 00:31:01,800 --> 00:30:59,290 second ammonia tank right and there has 591 00:31:04,080 --> 00:31:01,810 there being a schedule right there to 592 00:31:06,270 --> 00:31:04,090 get scheduled pressure to get get that 593 00:31:08,340 --> 00:31:06,280 initiated so I think that they got in a 594 00:31:10,890 --> 00:31:08,350 hurry and they initiated without going 595 00:31:12,510 --> 00:31:10,900 to mal seizure with a contact and say 596 00:31:13,620 --> 00:31:12,520 I'm more about to initiate wow so 597 00:31:15,420 --> 00:31:13,630 there's another another piece of an 598 00:31:16,710 --> 00:31:15,430 error change you got some some guys on 599 00:31:18,360 --> 00:31:16,720 the other end her feelings and schedule 600 00:31:21,270 --> 00:31:18,370 pressure we've got some procedures that 601 00:31:23,730 --> 00:31:21,280 weren't synced up to calm but wasn't 602 00:31:25,830 --> 00:31:23,740 synced up people starting to get 603 00:31:27,630 --> 00:31:25,840 distracted with the plaque King there 604 00:31:30,680 --> 00:31:27,640 was a lot of a lot of variables going on 605 00:31:33,570 --> 00:31:30,690 in there and I captured that really well 606 00:31:36,390 --> 00:31:33,580 I didn't realize that that all that was 607 00:31:38,460 --> 00:31:36,400 going on and even listening to the to 608 00:31:40,710 --> 00:31:38,470 the recording I didn't realize you could 609 00:31:42,660 --> 00:31:40,720 guys had you guys had obstacles out in 610 00:31:45,630 --> 00:31:42,670 front of you didn't know about right 611 00:31:48,270 --> 00:31:45,640 yeah that's really good in hindsight is 612 00:31:53,130 --> 00:31:48,280 always 20/20 I I wish that I would have 613 00:32:01,350 --> 00:31:58,500 KSC end to have a better handoff and I 614 00:32:04,680 --> 00:32:01,360 think we did improve on that a lot after 615 00:32:18,480 --> 00:32:04,690 after that right right let's see what 616 00:32:19,919 --> 00:32:18,490 else so sounds like EPS is freaking out 617 00:32:23,460 --> 00:32:19,929 a little bit but you know it's it's 618 00:32:25,200 --> 00:32:23,470 gonna get better here I was like I I 619 00:32:26,850 --> 00:32:25,210 don't know if it was out of ignorance or 620 00:32:30,060 --> 00:32:26,860 not but I was less concerned about it 621 00:32:32,549 --> 00:32:30,070 then then Larry was at the at the time 622 00:32:33,900 --> 00:32:32,559 yes and you knew you had you had one 623 00:32:35,549 --> 00:32:33,910 friendly pup senior you had some cool 624 00:32:38,100 --> 00:32:35,559 you remember what the kW was about that 625 00:32:40,380 --> 00:32:38,110 time I think he was saying for about 626 00:32:42,480 --> 00:32:40,390 four probably are never fuel stuff for 627 00:32:44,159 --> 00:32:42,490 that fuel cell right I see but so if 628 00:32:45,840 --> 00:32:44,169 there even is probably about 12 or so 629 00:32:48,120 --> 00:32:45,850 right yeah so one friend lives should be 630 00:33:13,600 --> 00:32:48,130 able to handle handle 12 pretty well 631 00:33:18,019 --> 00:33:15,019 yeah 632 00:33:28,310 --> 00:33:18,029 here we see cooling on now or go to 633 00:33:46,399 --> 00:33:28,320 think free only to to pump I just I 634 00:33:49,430 --> 00:33:46,409 couldn't take freon pump so as quickly 635 00:33:50,659 --> 00:33:49,440 as it came and almost subsided and 636 00:33:53,029 --> 00:33:50,669 forget all about you right 637 00:33:54,830 --> 00:33:53,039 yeah like when said that since that was 638 00:34:00,409 --> 00:33:54,840 the Vox I think the pain lasted a little 639 00:34:01,759 --> 00:34:00,419 bit yeah this is a box this is what we 640 00:34:04,759 --> 00:34:01,769 got about nine and a half minutes there 641 00:34:06,320 --> 00:34:04,769 so unboxed how long do you think the 642 00:34:08,659 --> 00:34:06,330 situation really went about double that 643 00:34:13,240 --> 00:34:08,669 maybe your you'll recall that's probably 644 00:34:16,010 --> 00:34:13,250 yes right let's excellent any other 645 00:34:17,599 --> 00:34:16,020 summary thoughts about the situation he 646 00:34:20,210 --> 00:34:17,609 gave a lot of hindsight while you were 647 00:34:23,740 --> 00:34:20,220 well we were going but any any other 648 00:34:26,089 --> 00:34:23,750 thoughts about the situation I guess 649 00:34:28,819 --> 00:34:26,099 some of the things that came from this 650 00:34:32,149 --> 00:34:28,829 mission and like we talked about like 651 00:34:34,909 --> 00:34:32,159 rule one last one got changed we started 652 00:34:37,849 --> 00:34:34,919 to Train post-landing we spent a lot of 653 00:34:40,129 --> 00:34:37,859 time with the KSC folks trying to 654 00:34:42,319 --> 00:34:40,139 establish better protocols and 655 00:34:48,379 --> 00:34:42,329 communication between the e common 656 00:34:51,819 --> 00:34:48,389 ground and the ground convoy guys we we 657 00:34:54,980 --> 00:34:51,829 improved the about t-mobile procedure a 658 00:35:00,710 --> 00:34:54,990 lot of improvements on how to go through 659 00:35:05,540 --> 00:35:00,720 it what else to do we your Miami stuff I 660 00:35:07,010 --> 00:35:05,550 long there was a lot of improvements on 661 00:35:08,690 --> 00:35:07,020 how oh and the communication with the 662 00:35:11,540 --> 00:35:08,700 flight director stressing with them that 663 00:35:13,970 --> 00:35:11,550 hey look at the vehicle here's what 664 00:35:16,520 --> 00:35:13,980 under temp occurs this is why we're so 665 00:35:17,500 --> 00:35:16,530 scared of it and they in the flight 666 00:35:19,180 --> 00:35:17,510 Richards in a lot 667 00:35:21,310 --> 00:35:19,190 better job post-landing to make sure the 668 00:35:24,040 --> 00:35:21,320 team is cognizant hey not me ain't 669 00:35:27,190 --> 00:35:24,050 handing over until keep the room quiet 670 00:35:30,790 --> 00:35:27,200 until around who's established and the 671 00:35:32,860 --> 00:35:30,800 crews out itself sometimes even when the 672 00:35:35,620 --> 00:35:32,870 missions seemingly over it may not be 673 00:35:37,750 --> 00:35:35,630 over in the midst of distraction the 674 00:35:40,540 --> 00:35:37,760 EECOM team identified the under temp 675 00:35:42,600 --> 00:35:40,550 situation diagnose the cause of two 676 00:35:45,310 --> 00:35:42,610 cooling systems running simultaneously 677 00:35:47,380 --> 00:35:45,320 then resolve the situation while 678 00:35:50,500 --> 00:35:47,390 preserving crew safety and all vehicle 679 00:35:52,480 --> 00:35:50,510 hardware the mcc flight controller is 680 00:35:55,780 --> 00:35:52,490 one who must always be aware that 681 00:35:57,130 --> 00:35:55,790 suddenly and unexpectedly we may find 682 00:35:59,250 --> 00:35:57,140 ourselves in a role where our 683 00:36:02,580 --> 00:35:59,260 performance has ultimate consequences 684 00:36:05,740 --> 00:36:02,590 discipline competence confidence 685 00:36:08,290 --> 00:36:05,750 responsibility toughness teamwork and 686 00:36:10,450 --> 00:36:08,300 vigilance these are our core values 687 00:36:12,400 --> 00:36:10,460 values that have served us well 688 00:36:14,320 --> 00:36:12,410 values that have allowed us to slip the
