1 00:00:15,709 --> 00:00:13,339 when I think about 1969 and I look back 2 00:00:18,350 --> 00:00:15,719 you know a hair right now in the back of 3 00:00:21,409 --> 00:00:18,360 my neck is arising because I remember 4 00:00:23,029 --> 00:00:21,419 those days was really the focus of what 5 00:00:26,269 --> 00:00:23,039 we have been preparing for after 6 00:00:28,490 --> 00:00:26,279 President Kennedy had really charted us 7 00:00:30,220 --> 00:00:28,500 as now so to try to send somebody to the 8 00:00:34,280 --> 00:00:30,230 moon and bring him back safely and 9 00:00:36,140 --> 00:00:34,290 really when the words were said you know 10 00:00:38,000 --> 00:00:36,150 they just said rang a bell with me after 11 00:00:40,369 --> 00:00:38,010 all those years and the hard work and 12 00:00:43,130 --> 00:00:40,379 the sweat the blood looking all the 13 00:00:45,079 --> 00:00:43,140 problems that we had been through so 14 00:00:47,119 --> 00:00:45,089 there's no question if you go back and 15 00:00:49,520 --> 00:00:47,129 look in history and I'm a history buff 16 00:00:51,890 --> 00:00:49,530 by the way and I look at what we've done 17 00:00:53,810 --> 00:00:51,900 really with the lunar landing I think I 18 00:00:56,030 --> 00:00:53,820 don't know of anything that it's greater 19 00:00:58,399 --> 00:00:56,040 than that you think about wars and you 20 00:01:00,410 --> 00:00:58,409 think about back in history and a lot of 21 00:01:03,530 --> 00:01:00,420 the things that's happened but if you 22 00:01:04,670 --> 00:01:03,540 think about human endeavor I don't know 23 00:01:11,100 --> 00:01:04,680 of anything when you talk about 24 00:01:15,360 --> 00:01:14,070 well we have to go back a few years if 25 00:01:18,330 --> 00:01:15,370 you want to look at what made the 26 00:01:21,150 --> 00:01:18,340 program successful and I have to give 27 00:01:23,160 --> 00:01:21,160 the German team really the credit and I 28 00:01:24,960 --> 00:01:23,170 started with a lot of them in early 50s 29 00:01:27,600 --> 00:01:24,970 because we were with the army in those 30 00:01:30,870 --> 00:01:27,610 days and of course 1960 we went to NASA 31 00:01:32,430 --> 00:01:30,880 but a lot of work had begun von Braun 32 00:01:34,740 --> 00:01:32,440 was always interest in space travel 33 00:01:36,780 --> 00:01:34,750 he didn't care a thing about military he 34 00:01:38,970 --> 00:01:36,790 didn't care the thing about ballistic 35 00:01:41,850 --> 00:01:38,980 missiles and so forth but of course he 36 00:01:43,469 --> 00:01:41,860 came over here with the paperclip when 37 00:01:44,219 --> 00:01:43,479 we brought two people over after World 38 00:01:46,469 --> 00:01:44,229 War two 39 00:01:49,650 --> 00:01:46,479 the German team when they came here to 40 00:01:52,110 --> 00:01:49,660 redstone and started just extending the 41 00:01:54,150 --> 00:01:52,120 v2 the old v2 rocket that they had built 42 00:01:56,730 --> 00:01:54,160 in fact he was the key person in that 43 00:01:58,530 --> 00:01:56,740 and we went to the Redstone muscle then 44 00:02:01,290 --> 00:01:58,540 after that that was about a hundred 45 00:02:02,910 --> 00:02:01,300 seventy-five nautical mile listing 46 00:02:04,350 --> 00:02:02,920 missile and after that was a Jupiter 47 00:02:06,180 --> 00:02:04,360 missile which was an intermediate-range 48 00:02:09,240 --> 00:02:06,190 ballistic missile fifteen hundred miles 49 00:02:11,130 --> 00:02:09,250 we all worked on that then the idea came 50 00:02:13,199 --> 00:02:11,140 up with he really wanted to build 51 00:02:15,990 --> 00:02:13,209 something big that he could go into 52 00:02:17,520 --> 00:02:16,000 space and carry some heavy payloads so 53 00:02:20,220 --> 00:02:17,530 we started looking at how does one 54 00:02:22,470 --> 00:02:20,230 cluster we took the tanks from the 55 00:02:24,630 --> 00:02:22,480 Redstone 70 inches in diameter we took 56 00:02:26,520 --> 00:02:24,640 the Jupiter which was I in a minute 57 00:02:29,430 --> 00:02:26,530 range here immediate range ballistic 58 00:02:32,100 --> 00:02:29,440 missile it had 105 inch in diameter and 59 00:02:34,410 --> 00:02:32,110 then with clustered goals and we was 60 00:02:37,320 --> 00:02:34,420 able to cluster an engine we had eight 61 00:02:40,020 --> 00:02:37,330 engines nine tanks now think about how 62 00:02:41,940 --> 00:02:40,030 do you get the propellants and for for 63 00:02:44,250 --> 00:02:41,950 the benefit let's say of people they may 64 00:02:46,740 --> 00:02:44,260 not know how rocket engine works but you 65 00:02:48,690 --> 00:02:46,750 have to have a fuel and oxidizer when 66 00:02:50,370 --> 00:02:48,700 you go up into space is no air up there 67 00:02:52,680 --> 00:02:50,380 like an airplane or a jet engine 68 00:02:55,140 --> 00:02:52,690 wouldn't require so we care oxidizer and 69 00:02:56,820 --> 00:02:55,150 most of time we use liquid oxygen and 70 00:02:59,490 --> 00:02:56,830 the fuel can be different things your 71 00:03:02,310 --> 00:02:59,500 automobile uses gasoline back in those 72 00:03:03,930 --> 00:03:02,320 days we use alcohol 75% alcohol 73 00:03:08,340 --> 00:03:03,940 there's a few and then we went to 74 00:03:10,800 --> 00:03:08,350 Keirsey and rp1 or jet fuel but we had 75 00:03:12,570 --> 00:03:10,810 to design the system and we clustered 76 00:03:14,370 --> 00:03:12,580 the tanks and you had to manifold all 77 00:03:16,320 --> 00:03:14,380 these system you get both the oxidizing 78 00:03:18,090 --> 00:03:16,330 the fuel to the individual engine but if 79 00:03:20,280 --> 00:03:18,100 you got eight engines you can imagine 80 00:03:21,930 --> 00:03:20,290 what a plumber's nightmare you had and 81 00:03:23,910 --> 00:03:21,940 you had cross feed you're worried about 82 00:03:24,809 --> 00:03:23,920 one engine would do something to the 83 00:03:26,550 --> 00:03:24,819 engine adjacent 84 00:03:29,970 --> 00:03:26,560 to it whether it was the feed system or 85 00:03:31,979 --> 00:03:29,980 was vibrations or whatever so we went 86 00:03:33,959 --> 00:03:31,989 through a lot of testing to do that in 87 00:03:36,270 --> 00:03:33,969 addition to clustering engines then you 88 00:03:37,949 --> 00:03:36,280 had to pressurize the tanks once you 89 00:03:39,420 --> 00:03:37,959 start taking the propellants out if you 90 00:03:41,550 --> 00:03:39,430 don't continue to put the pressure in 91 00:03:43,170 --> 00:03:41,560 there the tank will collapse so we had 92 00:03:45,509 --> 00:03:43,180 pressurization system we had to design 93 00:03:47,670 --> 00:03:45,519 and we went through a lot of tests here 94 00:03:49,349 --> 00:03:47,680 at our Center to develop these systems 95 00:03:50,759 --> 00:03:49,359 we did a lot of the analysis and 96 00:03:52,890 --> 00:03:50,769 everything in fact I had worked in 97 00:03:54,449 --> 00:03:52,900 propulsion and that's why I keep 98 00:03:56,069 --> 00:03:54,459 referring to the engines and a 99 00:03:58,530 --> 00:03:56,079 propulsion system because that that's 100 00:03:59,520 --> 00:03:58,540 the experience I had acquired back 101 00:04:02,789 --> 00:03:59,530 during those years 102 00:04:05,970 --> 00:04:02,799 well after we flew we flew some 10 of 103 00:04:07,649 --> 00:04:05,980 those the old Saturn 1 Saturn 1b after 104 00:04:10,679 --> 00:04:07,659 we clustered them and we went to a 105 00:04:12,839 --> 00:04:10,689 second stage and we went to a high 106 00:04:15,629 --> 00:04:12,849 energy system so far as the engine 107 00:04:18,509 --> 00:04:15,639 performance and used liquid hydrogen as 108 00:04:19,680 --> 00:04:18,519 a few still liquid oxygen is oxidized 109 00:04:21,479 --> 00:04:19,690 now you say why do you use liquid 110 00:04:23,879 --> 00:04:21,489 hydrogen if you remember your chemistry 111 00:04:26,430 --> 00:04:23,889 will it has a molecular weight of two in 112 00:04:29,399 --> 00:04:26,440 terms of performance it gives you the 113 00:04:31,080 --> 00:04:29,409 highest performance and we that was new 114 00:04:33,420 --> 00:04:31,090 to us in those days no one had used 115 00:04:35,339 --> 00:04:33,430 liquid hydrogen as a fuel you got to 116 00:04:38,430 --> 00:04:35,349 recognize the liquid oxygen is at minus 117 00:04:40,740 --> 00:04:38,440 297 degrees Fahrenheit cried genie the 118 00:04:42,360 --> 00:04:40,750 liquid hydrogen is minus 421 degrees 119 00:04:44,370 --> 00:04:42,370 well that brings in a lot of problems 120 00:04:46,020 --> 00:04:44,380 how do you maintain that you don't have 121 00:04:48,180 --> 00:04:46,030 a vacuum bottle or something you have 122 00:04:50,969 --> 00:04:48,190 insulation you have to be concerned with 123 00:04:53,070 --> 00:04:50,979 in addition you have problems of getting 124 00:04:55,529 --> 00:04:53,080 the propellant at the right conditions 125 00:04:57,629 --> 00:04:55,539 for the engine in your car your car does 126 00:04:59,399 --> 00:04:57,639 what use gasoline you have a carburetor 127 00:05:02,279 --> 00:04:59,409 and you take air from the atmosphere you 128 00:05:04,409 --> 00:05:02,289 atomized the gasoline and you force it 129 00:05:06,629 --> 00:05:04,419 into your combustion chamber you have a 130 00:05:09,480 --> 00:05:06,639 spark plug too United with very similar 131 00:05:11,760 --> 00:05:09,490 and a rocket engine okay we have pumps 132 00:05:13,680 --> 00:05:11,770 to do them the same thing where we take 133 00:05:15,870 --> 00:05:13,690 the oxidizer from a few we ignite a lot 134 00:05:18,149 --> 00:05:15,880 of times with the spark spark igniter we 135 00:05:20,850 --> 00:05:18,159 call it then we have what we call an 136 00:05:23,399 --> 00:05:20,860 injector face plate that atomizer 137 00:05:25,290 --> 00:05:23,409 instead of a carburetor in fact it's a 138 00:05:27,270 --> 00:05:25,300 lot simpler we don't have Pistons like 139 00:05:30,120 --> 00:05:27,280 you have in a in an automobile or 140 00:05:31,860 --> 00:05:30,130 internal combustion engine so but you 141 00:05:33,330 --> 00:05:31,870 get into problems if you're familiar 142 00:05:34,890 --> 00:05:33,340 with some of the problems you have your 143 00:05:36,779 --> 00:05:34,900 car some time you turn the switch off 144 00:05:38,400 --> 00:05:36,789 when you hear a pin and it won't stop 145 00:05:40,610 --> 00:05:38,410 it's sort of decently 146 00:05:45,300 --> 00:05:40,620 well we call it combustion instability 147 00:05:47,310 --> 00:05:45,310 in the case of a lot of the hydrocarbon 148 00:05:48,870 --> 00:05:47,320 engines you can get involved with that 149 00:05:51,180 --> 00:05:48,880 where you don't get complete combustion 150 00:05:54,810 --> 00:05:51,190 and alas you sit there and destroy 151 00:05:56,280 --> 00:05:54,820 itself it goes into the various modes of 152 00:05:58,680 --> 00:05:56,290 vibration modes and I'll sit there and 153 00:06:00,660 --> 00:05:58,690 destroy itself and as we move from the 154 00:06:02,370 --> 00:06:00,670 Saturn one I want to make the point as 155 00:06:05,280 --> 00:06:02,380 we go to the Saturn five which is what 156 00:06:08,220 --> 00:06:05,290 we use for the Apollo this one see the 157 00:06:09,600 --> 00:06:08,230 first stage use five f1 engine each 158 00:06:12,150 --> 00:06:09,610 engine had a thrust of something like 159 00:06:14,070 --> 00:06:12,160 1/2 million pounds so we had five of 160 00:06:16,170 --> 00:06:14,080 those which gave you seven million 161 00:06:19,080 --> 00:06:16,180 pounds thrust well you needed that to 162 00:06:21,240 --> 00:06:19,090 get all this mass off and it uses liquid 163 00:06:23,880 --> 00:06:21,250 oxygen and that was a new engine now is 164 00:06:25,980 --> 00:06:23,890 a huge engine but we had all kind of 165 00:06:28,380 --> 00:06:25,990 problems in early days name of this 166 00:06:30,570 --> 00:06:28,390 combustion instability and now if you 167 00:06:32,760 --> 00:06:30,580 can envision an injector plate some 168 00:06:35,790 --> 00:06:32,770 three feet in diameter with all these 169 00:06:37,350 --> 00:06:35,800 holes at it we had problems with the 170 00:06:38,760 --> 00:06:37,360 thing in fact we spent over thirty 171 00:06:40,590 --> 00:06:38,770 million dollars has some of the best 172 00:06:43,770 --> 00:06:40,600 brains in the country helped us on this 173 00:06:46,380 --> 00:06:43,780 same had teams working it some people in 174 00:06:47,940 --> 00:06:46,390 fact with the presidential scientific 175 00:06:50,130 --> 00:06:47,950 committee said you'd never get an engine 176 00:06:52,440 --> 00:06:50,140 that large to run the Russians nobody 177 00:06:54,150 --> 00:06:52,450 ever built an engine at large and 178 00:06:56,160 --> 00:06:54,160 therefore we were kind of the first one 179 00:06:57,870 --> 00:06:56,170 but combustion instability almost 180 00:07:01,290 --> 00:06:57,880 brought us to our knees we set up 181 00:07:03,090 --> 00:07:01,300 special teams and with our contractor 182 00:07:05,700 --> 00:07:03,100 Rocketdyne which is the vision north 183 00:07:08,100 --> 00:07:05,710 american back then and we had people 184 00:07:10,590 --> 00:07:08,110 from nasa and i participated and a lot 185 00:07:12,150 --> 00:07:10,600 of that myself personally but a lot of 186 00:07:14,730 --> 00:07:12,160 work was done and make a long story 187 00:07:17,220 --> 00:07:14,740 short if you visualize them and a flat 188 00:07:19,560 --> 00:07:17,230 placement a flat plate injector and we 189 00:07:22,920 --> 00:07:19,570 put baffles in there and you wanted to 190 00:07:24,840 --> 00:07:22,930 be sure that they could attenuate or 191 00:07:26,100 --> 00:07:24,850 dampen any kind of oscillations well 192 00:07:28,620 --> 00:07:26,110 then what we would do it put a little 193 00:07:30,960 --> 00:07:28,630 bomb we would put a little bomb and then 194 00:07:32,760 --> 00:07:30,970 set that bomb off during the firing and 195 00:07:35,010 --> 00:07:32,770 we do this on a test stand but we should 196 00:07:37,620 --> 00:07:35,020 do like tests right here in our single 197 00:07:39,480 --> 00:07:37,630 engine test stand on our test area and 198 00:07:41,730 --> 00:07:39,490 we set this bomb off and see how long it 199 00:07:43,470 --> 00:07:41,740 would take to dampen and if it would 200 00:07:45,240 --> 00:07:43,480 dampen with the various configurations 201 00:07:47,640 --> 00:07:45,250 that we felt like we had a dynamically 202 00:07:49,230 --> 00:07:47,650 stable injector and eventually we were 203 00:07:51,690 --> 00:07:49,240 able to do that it took months and 204 00:07:53,460 --> 00:07:51,700 months months to do that 205 00:07:54,800 --> 00:07:53,470 in addition you have problem with pumps 206 00:07:57,030 --> 00:07:54,810 and you think about turbomachinery 207 00:07:59,130 --> 00:07:57,040 because we take the propellants from the 208 00:08:01,830 --> 00:07:59,140 tank and we're driving them into the 209 00:08:03,660 --> 00:08:01,840 combustion chamber at high pressures the 210 00:08:05,280 --> 00:08:03,670 combustion chamber pressure on f1 is 211 00:08:08,160 --> 00:08:05,290 about a thousand pounds per square inch 212 00:08:10,260 --> 00:08:08,170 which was really unknown in those days a 213 00:08:12,390 --> 00:08:10,270 high Swede meant something like full 500 214 00:08:15,000 --> 00:08:12,400 pounds per square inch so as you grew up 215 00:08:17,640 --> 00:08:15,010 in pressures that meanness move 40 more 216 00:08:21,000 --> 00:08:17,650 problems associated with your turbines 217 00:08:22,560 --> 00:08:21,010 we pump the impellers etc so all those 218 00:08:25,470 --> 00:08:22,570 problems had to be worked had to be 219 00:08:27,840 --> 00:08:25,480 looked at and we we blew up a lot of 220 00:08:29,760 --> 00:08:27,850 lakhs of liquid oxygen pumps a lot of 221 00:08:32,010 --> 00:08:29,770 pumps we blow up and there's nothing 222 00:08:33,750 --> 00:08:32,020 like if you can visualize when you have 223 00:08:35,700 --> 00:08:33,760 liquid oxygen and you know about welding 224 00:08:37,469 --> 00:08:35,710 and they use the settling you know when 225 00:08:38,969 --> 00:08:37,479 he's cutting a piece of steel there was 226 00:08:41,160 --> 00:08:38,979 he do he presses the button for more 227 00:08:43,230 --> 00:08:41,170 oxygen there and that's the thing it 228 00:08:45,180 --> 00:08:43,240 gives you the high heat of course we've 229 00:08:46,590 --> 00:08:45,190 got oxygen there if you get a fire going 230 00:08:48,690 --> 00:08:46,600 look out because it's gone 231 00:08:50,640 --> 00:08:48,700 everything around it's gone there's 232 00:08:52,680 --> 00:08:50,650 nothing as serious as a liquid oxygen 233 00:08:55,320 --> 00:08:52,690 pump explosion and we had many of those 234 00:08:57,000 --> 00:08:55,330 in those days but we had barring problem 235 00:08:59,250 --> 00:08:57,010 and turbine blade problems that we had 236 00:09:02,280 --> 00:08:59,260 to overcome and there was many years 237 00:09:04,620 --> 00:09:02,290 that we we worked and I when I say we 238 00:09:06,680 --> 00:09:04,630 work we NASA with our contractors and in 239 00:09:08,850 --> 00:09:06,690 braining consultants we had academia 240 00:09:09,360 --> 00:09:08,860 assisting us and helping us in all these 241 00:09:12,420 --> 00:09:09,370 areas 242 00:09:15,150 --> 00:09:12,430 it was long hours I mean blood and sweat 243 00:09:17,520 --> 00:09:15,160 on the road a lot traveling we had a 244 00:09:19,050 --> 00:09:17,530 test dance for the f1 and it was Air 245 00:09:23,160 --> 00:09:19,060 Force Base where we land Space Shuttle 246 00:09:24,780 --> 00:09:23,170 now at big test stands out there we had 247 00:09:27,270 --> 00:09:24,790 explosions there in reqtest and 248 00:09:30,030 --> 00:09:27,280 sometimes and eventually was able to do 249 00:09:31,680 --> 00:09:30,040 testing here at Marshall and then one 250 00:09:34,140 --> 00:09:31,690 with cluster the engine we actually did 251 00:09:36,120 --> 00:09:34,150 the cluster tests out here what we call 252 00:09:38,430 --> 00:09:36,130 the s1 see that was the first stage of 253 00:09:40,410 --> 00:09:38,440 Saturn and with cluster the engines and 254 00:09:41,760 --> 00:09:40,420 did all static fire in fact built the 255 00:09:43,890 --> 00:09:41,770 first stages they brought all the 256 00:09:46,140 --> 00:09:43,900 hardware here brought the engines and we 257 00:09:49,410 --> 00:09:46,150 did all the cluster tests here initially 258 00:09:51,660 --> 00:09:49,420 and eventually once we froze the design 259 00:09:54,210 --> 00:09:51,670 and then we brought Boeing in as a prime 260 00:09:56,310 --> 00:09:54,220 contractor to actually pick up and do 261 00:09:57,690 --> 00:09:56,320 the design in New Orleans and build the 262 00:10:00,300 --> 00:09:57,700 hardware down there and now we would 263 00:10:02,520 --> 00:10:00,310 barge all the hardware you imagine 33 264 00:10:09,300 --> 00:10:02,530 foot in diameter the tank was 33 feet in 265 00:10:15,749 --> 00:10:13,290 the second stage again used a new engine 266 00:10:18,990 --> 00:10:15,759 what we call the j2 engine it was a 267 00:10:21,329 --> 00:10:19,000 liquid oxygen liquid hydrogen engine the 268 00:10:22,559 --> 00:10:21,339 one I'd mentioned earlier was 15,000 269 00:10:25,530 --> 00:10:22,569 pounds thrust this one had around 270 00:10:27,269 --> 00:10:25,540 200,000 pounds now we had five of them 271 00:10:29,910 --> 00:10:27,279 which gave us a million pounds in the 272 00:10:31,980 --> 00:10:29,920 second stage and what you do you'd burn 273 00:10:33,960 --> 00:10:31,990 the first stage for about 130 seconds 274 00:10:35,249 --> 00:10:33,970 first stage was separating dropping 275 00:10:38,040 --> 00:10:35,259 ocean the second stage would have 276 00:10:40,499 --> 00:10:38,050 ignited igniting and it would burn for 277 00:10:42,809 --> 00:10:40,509 some five or six minutes and then all 278 00:10:44,490 --> 00:10:42,819 you're doing is adding impulse or energy 279 00:10:45,689 --> 00:10:44,500 to the whole system and of course the 280 00:10:48,059 --> 00:10:45,699 payload up there is what you're 281 00:10:51,030 --> 00:10:48,069 interested in and we had problems with 282 00:10:52,920 --> 00:10:51,040 the second stage a lot of problems in 283 00:10:55,079 --> 00:10:52,930 terms of propellant conditioning as I 284 00:10:56,730 --> 00:10:55,089 mentioned earlier you have to have the 285 00:10:59,309 --> 00:10:56,740 propellants at the right temperature and 286 00:11:07,350 --> 00:10:59,319 pressure for the pumps and again we're 287 00:11:09,150 --> 00:11:07,360 at cryogenic temperature at night a 288 00:11:12,300 --> 00:11:09,160 Mississippi test facility which is 289 00:11:14,639 --> 00:11:12,310 Stennis Space Center today I spent a lot 290 00:11:17,220 --> 00:11:14,649 of time I said personally in Downey 291 00:11:19,949 --> 00:11:17,230 California with the first what we call 292 00:11:22,319 --> 00:11:19,959 the t-bird that was a second stage test 293 00:11:25,889 --> 00:11:22,329 bird call it the bird because it's going 294 00:11:27,629 --> 00:11:25,899 to fly but we did a lot of testing down 295 00:11:29,790 --> 00:11:27,639 here but what they did after they built 296 00:11:31,679 --> 00:11:29,800 it we had a milestone we've committed 297 00:11:33,960 --> 00:11:31,689 with Congress and with everybody to get 298 00:11:35,699 --> 00:11:33,970 ready for them the lunar mission so we 299 00:11:37,769 --> 00:11:35,709 actually shipped this hardware 300 00:11:41,519 --> 00:11:37,779 well von Braun is one of the funny 301 00:11:43,410 --> 00:11:41,529 stores with von Braun he invites all the 302 00:11:46,049 --> 00:11:43,420 big shots from Washington Administrator 303 00:11:48,090 --> 00:11:46,059 and all of them and they all fly into 304 00:11:52,410 --> 00:11:48,100 Gulfport Mississippi and our test site 305 00:11:54,629 --> 00:11:52,420 is near Picayune Mississippi and the 306 00:11:56,309 --> 00:11:54,639 base manager there was Jack bolt he was 307 00:11:58,079 --> 00:11:56,319 our base manager so what does he do he 308 00:12:00,059 --> 00:11:58,089 gets the Highway Patrol and state of 309 00:12:02,129 --> 00:12:00,069 Mississippi and also in state Louisiana 310 00:12:04,799 --> 00:12:02,139 and they set a world record drive from 311 00:12:07,019 --> 00:12:04,809 Airport up to the stent up to the the 312 00:12:08,460 --> 00:12:07,029 site there for the test course everybody 313 00:12:10,740 --> 00:12:08,470 was all uptight because that was gonna 314 00:12:12,689 --> 00:12:10,750 be the first test on the second stage 315 00:12:15,660 --> 00:12:12,699 where we we finally got a good test off 316 00:12:18,509 --> 00:12:15,670 that night made many tips down there but 317 00:12:20,069 --> 00:12:18,519 eventually what happened well they over 318 00:12:22,930 --> 00:12:20,079 pressurized the tank and the tank was 319 00:12:24,490 --> 00:12:22,940 destroyed we had investigation 320 00:12:29,380 --> 00:12:24,500 knew what was the problem when we fixed 321 00:12:34,150 --> 00:12:31,660 third stage was built by McDonnell 322 00:12:37,270 --> 00:12:34,160 Douglas Huntington Beach and their 323 00:12:39,010 --> 00:12:37,280 testing was up in Sacramento they had a 324 00:12:40,750 --> 00:12:39,020 test facility up there and had a single 325 00:12:42,970 --> 00:12:40,760 engine the one engine 326 00:12:46,360 --> 00:12:42,980 like I mentioned on the second stage the 327 00:12:48,160 --> 00:12:46,370 j2 in they had one and eventually they 328 00:12:51,490 --> 00:12:48,170 had a problem up there was on the engine 329 00:12:53,170 --> 00:12:51,500 so von Braun he bars Casey's airplane 330 00:12:56,470 --> 00:12:53,180 and it was a dose to go out on that 331 00:12:58,090 --> 00:12:56,480 thing it was a a Lockheed Jetstar well 332 00:12:59,590 --> 00:12:58,100 here's a young engineer and ever been on 333 00:13:02,920 --> 00:12:59,600 that little jet engine and all jet 334 00:13:05,860 --> 00:13:02,930 airplane and everything and we went from 335 00:13:08,890 --> 00:13:05,870 Huntsville Redstone out here to Van Nuys 336 00:13:12,700 --> 00:13:08,900 to our contractor and you owned up to 337 00:13:15,250 --> 00:13:12,710 Sacramento went out to test and we set 338 00:13:19,000 --> 00:13:15,260 up investigation see what we need to do 339 00:13:20,470 --> 00:13:19,010 and so we got ready to come by and they 340 00:13:23,080 --> 00:13:20,480 had a Stewart on there and they were 341 00:13:25,120 --> 00:13:23,090 lucky contractors but I asked young 342 00:13:26,980 --> 00:13:25,130 fellow I said can you tell me something 343 00:13:28,510 --> 00:13:26,990 about the jet engine what the thrust is 344 00:13:30,760 --> 00:13:28,520 or something I said I got a son I like 345 00:13:32,470 --> 00:13:30,770 to tell him about this and I was just 346 00:13:34,600 --> 00:13:32,480 like a kid with a new toy being on this 347 00:13:36,310 --> 00:13:34,610 airplane so he went off about ten 348 00:13:39,960 --> 00:13:36,320 minutes he came back and he gave me this 349 00:13:42,100 --> 00:13:39,970 little brochure and it had all the 350 00:13:44,530 --> 00:13:42,110 description of what the airplane would 351 00:13:47,770 --> 00:13:44,540 do cetera except well the last page in 352 00:13:50,200 --> 00:13:47,780 there was a certificate and it says this 353 00:13:52,810 --> 00:13:50,210 is this is to certify that Alexei McCool 354 00:13:54,490 --> 00:13:52,820 jr. blah blah blah date so-and-so did 355 00:13:56,800 --> 00:13:54,500 fly in Sacramento altitude so-and-so 356 00:13:58,840 --> 00:13:56,810 ground speed of so-and-so and the pilot 357 00:14:00,700 --> 00:13:58,850 signed it well I looked down and who was 358 00:14:02,650 --> 00:14:00,710 the pilot Wernher von Braun and I looked 359 00:14:04,330 --> 00:14:02,660 up him here what's coming from the 360 00:14:06,940 --> 00:14:04,340 cockpit up there and he had a big old 361 00:14:14,160 --> 00:14:06,950 grin on his face and he wasn't checked 362 00:14:19,350 --> 00:14:17,100 that was really you know they will do 363 00:14:21,840 --> 00:14:19,360 all this and us work with all the 364 00:14:22,440 --> 00:14:21,850 counterparts let's theater at JSC at 365 00:14:24,629 --> 00:14:22,450 Houston 366 00:14:26,879 --> 00:14:24,639 our friends down there and then 367 00:14:29,129 --> 00:14:26,889 integrate all of this including all the 368 00:14:30,990 --> 00:14:29,139 work at Kennedy Space Center because 369 00:14:32,600 --> 00:14:31,000 then you got all the launch complex to 370 00:14:34,740 --> 00:14:32,610 deal with you got all the propellant 371 00:14:37,019 --> 00:14:34,750 systems that you got to fill in drain 372 00:14:38,759 --> 00:14:37,029 the tanks etc you got all that launch 373 00:14:41,100 --> 00:14:38,769 commit criteria to deal with all 374 00:14:43,980 --> 00:14:41,110 electrical systems to deal with so it 375 00:14:47,639 --> 00:14:43,990 was a big job that went NASA we all had 376 00:14:49,230 --> 00:14:47,649 to really get involved with and it was 377 00:14:53,730 --> 00:14:49,240 very challenging a lot of meetings a lot 378 00:14:55,110 --> 00:14:53,740 of travel long hours von Braun was in 379 00:14:56,850 --> 00:14:55,120 the middle of all levels you know he's 380 00:14:59,310 --> 00:14:56,860 come around before we get down there 381 00:15:01,680 --> 00:14:59,320 like for our first flight which was what 382 00:15:04,889 --> 00:15:01,690 we call a s 501 that was our first one 383 00:15:07,829 --> 00:15:04,899 and eventually it flew we didn't have 384 00:15:10,710 --> 00:15:07,839 any problems on it second flight we did 385 00:15:13,500 --> 00:15:10,720 have some problems on the first stage we 386 00:15:16,740 --> 00:15:13,510 saw what we call pogo pogo as a as a 387 00:15:19,319 --> 00:15:16,750 vertical oscillation you can what 388 00:15:22,350 --> 00:15:19,329 happens there is the engine's natural 389 00:15:25,380 --> 00:15:22,360 frequency was around five cycles or five 390 00:15:28,259 --> 00:15:25,390 Hertz very very low frequency but it can 391 00:15:30,300 --> 00:15:28,269 couple with a structural frequency and 392 00:15:31,800 --> 00:15:30,310 it couldn't it can be bad or it could be 393 00:15:33,720 --> 00:15:31,810 uncomfortable for the astronauts were 394 00:15:36,509 --> 00:15:33,730 you actually sitting there so we had to 395 00:15:38,220 --> 00:15:36,519 come up with a design fix and to 396 00:15:39,750 --> 00:15:38,230 attenuate that and we were able to do 397 00:15:41,550 --> 00:15:39,760 that through the pre valves and all you 398 00:15:44,160 --> 00:15:41,560 had was cavities there that one 399 00:15:45,780 --> 00:15:44,170 attenuate and in fact today on Space 400 00:15:48,329 --> 00:15:45,790 Shuttle we have what we call Pogo 401 00:15:51,380 --> 00:15:48,339 suppressors so that was a new thing to 402 00:15:54,210 --> 00:15:51,390 us in addition on the second stage now 403 00:15:56,639 --> 00:15:54,220 we had some something neither lines that 404 00:15:59,189 --> 00:15:56,649 carried fuel and these were braided 405 00:16:02,370 --> 00:15:59,199 bellows and abraded was to allow them to 406 00:16:04,500 --> 00:16:02,380 articulate to move and everything and we 407 00:16:06,449 --> 00:16:04,510 noticed that the one of the engines shut 408 00:16:08,850 --> 00:16:06,459 down during flight but it's on our 409 00:16:12,389 --> 00:16:08,860 second Saturn 5 now this is scary you 410 00:16:14,280 --> 00:16:12,399 know he just started flying and pretty 411 00:16:17,160 --> 00:16:14,290 soon the other in just a second or so 412 00:16:18,809 --> 00:16:17,170 another engine shut down so there was 413 00:16:20,490 --> 00:16:18,819 three engines left and it continued to 414 00:16:23,400 --> 00:16:20,500 burn it burned longer because the 415 00:16:24,780 --> 00:16:23,410 propellant was still there and you still 416 00:16:26,460 --> 00:16:24,790 got the velocity and of course the 417 00:16:27,340 --> 00:16:26,470 guidance system was able to correct for 418 00:16:29,980 --> 00:16:27,350 this 419 00:16:33,280 --> 00:16:29,990 and eventually they separated and in 420 00:16:37,810 --> 00:16:33,290 third stage it went into a low Earth 421 00:16:40,510 --> 00:16:37,820 orbit and it was too restarted and it 422 00:16:42,100 --> 00:16:40,520 couldn't restart well we found out it 423 00:16:44,610 --> 00:16:42,110 was the same kind of problem here's this 424 00:16:47,710 --> 00:16:44,620 fuel line so we was able to go back and 425 00:16:49,480 --> 00:16:47,720 ascertain what had happened and when 426 00:16:50,770 --> 00:16:49,490 we've been testing you know test stance 427 00:16:53,710 --> 00:16:50,780 with this engine and here's this 428 00:16:55,930 --> 00:16:53,720 articulated line and it could get air 429 00:16:58,360 --> 00:16:55,940 that would liquefy and actually build up 430 00:17:00,610 --> 00:16:58,370 to ice and what you have if y'all 431 00:17:03,130 --> 00:17:00,620 familiar of what we call vortex shedding 432 00:17:05,050 --> 00:17:03,140 when you have bellows or something flow 433 00:17:06,490 --> 00:17:05,060 there and it actually would set up an 434 00:17:08,819 --> 00:17:06,500 oscillation it's a little bit like 435 00:17:11,949 --> 00:17:08,829 though familiar like a a chimney or uh 436 00:17:13,660 --> 00:17:11,959 smokestack the wind going around that 437 00:17:16,000 --> 00:17:13,670 will set up vortices and get it moving 438 00:17:18,460 --> 00:17:16,010 or bridges will do that so you try to 439 00:17:20,260 --> 00:17:18,470 design to stay away from that but that's 440 00:17:22,270 --> 00:17:20,270 that's exactly what happened we didn't 441 00:17:23,920 --> 00:17:22,280 know that we were able to test in a 442 00:17:26,260 --> 00:17:23,930 vacuum and prove that you didn't get the 443 00:17:29,350 --> 00:17:26,270 liquification to attenuate it so we 444 00:17:31,510 --> 00:17:29,360 actually got really the braids but on 445 00:17:34,920 --> 00:17:31,520 the next flight now which was kind of 446 00:17:37,960 --> 00:17:34,930 interesting he decided to go ahead and 447 00:17:40,270 --> 00:17:37,970 in fly you know man these were not man 448 00:17:42,400 --> 00:17:40,280 flights and that was a big one I 449 00:17:44,440 --> 00:17:42,410 remember we set the whole had all the 450 00:17:46,150 --> 00:17:44,450 corporate presidents here and all we 451 00:17:48,430 --> 00:17:46,160 keep people it was a meeting here at our 452 00:17:51,130 --> 00:17:48,440 Center all the people in Washington came 453 00:17:53,140 --> 00:17:51,140 down do we fly man on a next mission 454 00:17:55,870 --> 00:17:53,150 and he decided to go ahead and do that 455 00:17:58,870 --> 00:17:55,880 and then after that and they of course 456 00:18:01,390 --> 00:17:58,880 went around the moon and and of course 457 00:18:03,760 --> 00:18:01,400 Frank borman's thing that he did before 458 00:18:06,220 --> 00:18:03,770 Christmas and the one it really sticks 459 00:18:07,840 --> 00:18:06,230 with me is the guys on Christmas Eve 460 00:18:09,730 --> 00:18:07,850 when they went back to I'm getting goose 461 00:18:12,820 --> 00:18:09,740 bumps now thinking about they went to 462 00:18:14,470 --> 00:18:12,830 the book of Genesis and Frank starts out 463 00:18:16,210 --> 00:18:14,480 in the beginning you know God created 464 00:18:18,160 --> 00:18:16,220 heavens and earth and the guys actually 465 00:18:20,770 --> 00:18:18,170 they each one of the crew members they 466 00:18:22,810 --> 00:18:20,780 read parts of the creation account from 467 00:18:25,300 --> 00:18:22,820 the Bible on out today maybe that's a 468 00:18:27,610 --> 00:18:25,310 no-no I don't know but it really sticks 469 00:18:29,560 --> 00:18:27,620 for me to this day because it was 470 00:18:32,490 --> 00:18:29,570 Christmas Eve and here they've gone 471 00:18:34,930 --> 00:18:32,500 around the moon first time now anybody 472 00:18:36,730 --> 00:18:34,940 and of course that was a precursor for 473 00:18:38,440 --> 00:18:36,740 us being able to go to the moon you know 474 00:18:43,810 --> 00:18:38,450 we weren't sure what was involved in 475 00:18:49,180 --> 00:18:47,409 and he just let me use the words walk to 476 00:18:51,190 --> 00:18:49,190 talk okay you know what I mean by that 477 00:18:52,930 --> 00:18:51,200 he would come around you know you he 478 00:18:55,359 --> 00:18:52,940 would call or how the secretary called 479 00:18:57,099 --> 00:18:55,369 say he's coming over he just show up he 480 00:18:58,659 --> 00:18:57,109 come looking all the drawing board so 481 00:19:00,849 --> 00:18:58,669 what he got going on won't you design it 482 00:19:03,249 --> 00:19:00,859 this way that way but he was a people 483 00:19:05,169 --> 00:19:03,259 person he was really interested and I 484 00:19:06,700 --> 00:19:05,179 and I try to do that today myself I 485 00:19:07,960 --> 00:19:06,710 learned that from him you got to get 486 00:19:10,419 --> 00:19:07,970 around where the people are doing the 487 00:19:12,580 --> 00:19:10,429 work I mean sitting in your office or 488 00:19:14,080 --> 00:19:12,590 sitting in meetings well he did allow 489 00:19:16,119 --> 00:19:14,090 that don't misunderstand but he always 490 00:19:18,279 --> 00:19:16,129 used opportunity to get out and talk to 491 00:19:20,560 --> 00:19:18,289 the people people on the floor owned the 492 00:19:23,259 --> 00:19:20,570 shops how you doing it once you do it 493 00:19:26,499 --> 00:19:23,269 this way brilliant person very brain had 494 00:19:28,989 --> 00:19:26,509 all kinds of ideas you know good 495 00:19:30,700 --> 00:19:28,999 technical mind but if you go back to his 496 00:19:31,899 --> 00:19:30,710 early experience and I think that's 497 00:19:34,629 --> 00:19:31,909 that's the key here 498 00:19:37,269 --> 00:19:34,639 is keeping his hands dirty in other 499 00:19:39,249 --> 00:19:37,279 words when he was young you know he was 500 00:19:41,889 --> 00:19:39,259 involved in testing himself he was 501 00:19:43,690 --> 00:19:41,899 involved in design he had learned it the 502 00:19:45,219 --> 00:19:43,700 hard way just like you know working on 503 00:19:46,599 --> 00:19:45,229 your car you gonna learn yourself when 504 00:19:48,489 --> 00:19:46,609 you skinned your knuckles and everything 505 00:19:50,889 --> 00:19:48,499 he had done that he learned the hard way 506 00:19:53,680 --> 00:19:50,899 himself and he sort of preached that to 507 00:19:55,389 --> 00:19:53,690 us it's hands-on do you things hands-on 508 00:19:58,269 --> 00:19:55,399 and I think that's what made our center 509 00:20:01,049 --> 00:19:58,279 so great over the years is the hands-on 510 00:20:03,039 --> 00:20:01,059 work that we would do in-house 511 00:20:03,519 --> 00:20:03,049 capabilities that we have developed over 512 00:20:06,609 --> 00:20:03,529 the years 513 00:20:09,549 --> 00:20:06,619 blonde brawn always you know he exude 514 00:20:11,499 --> 00:20:09,559 this idea of teamwork now he had you 515 00:20:14,349 --> 00:20:11,509 know la to keep people of the Germans 516 00:20:16,239 --> 00:20:14,359 and they were our bosses and but they 517 00:20:17,950 --> 00:20:16,249 worked very well with us they just they 518 00:20:20,649 --> 00:20:17,960 were glad to have us was all part of the 519 00:20:22,810 --> 00:20:20,659 team there wasn't any partitions between 520 00:20:24,729 --> 00:20:22,820 us you could say what you want they 521 00:20:26,529 --> 00:20:24,739 wouldn't take it personal he's always 522 00:20:28,479 --> 00:20:26,539 building up the team building up for 523 00:20:30,070 --> 00:20:28,489 people but von Braun was able to do 524 00:20:33,310 --> 00:20:30,080 things like that he was able to go to 525 00:20:36,039 --> 00:20:33,320 Congress you know and articulate you 526 00:20:38,589 --> 00:20:36,049 know NASA's needs probably the charisma 527 00:20:41,080 --> 00:20:38,599 he had you know he knew this you really 528 00:20:42,580 --> 00:20:41,090 knew everything he was just so good and 529 00:20:44,409 --> 00:20:42,590 you got to think now here's this guy 530 00:20:47,049 --> 00:20:44,419 when he was in Germany in his days in 531 00:20:48,820 --> 00:20:47,059 his early 20s he was the technical 532 00:20:50,649 --> 00:20:48,830 director so there's no question you go 533 00:20:53,320 --> 00:20:50,659 read the history and everything well 534 00:20:55,389 --> 00:20:53,330 this this country I think if you go back 535 00:20:57,330 --> 00:20:55,399 and look we were so fortunate and 536 00:20:59,549 --> 00:20:57,340 getting him plus all his team 537 00:21:01,470 --> 00:20:59,559 that's not to say that the Russians 538 00:21:03,180 --> 00:21:01,480 didn't get quite a few they got a lot of 539 00:21:05,129 --> 00:21:03,190 production manufacturing but I believe 540 00:21:07,739 --> 00:21:05,139 that this country did well by getting 541 00:21:10,710 --> 00:21:07,749 him here and his team and I he was able 542 00:21:11,730 --> 00:21:10,720 to help all of us and he always had in 543 00:21:13,710 --> 00:21:11,740 his mind you know 544 00:21:16,440 --> 00:21:13,720 going to the moon who went out into 545 00:21:18,930 --> 00:21:16,450 space space exploration he always he 546 00:21:21,119 --> 00:21:18,940 would talk about their over and over and 547 00:21:23,489 --> 00:21:21,129 over and history is proving that if you 548 00:21:25,470 --> 00:21:23,499 look back now you look at Skylab I mean 549 00:21:27,119 --> 00:21:25,480 he was heavily involved in that which is 550 00:21:29,489 --> 00:21:27,129 really our first space station in this 551 00:21:31,529 --> 00:21:29,499 country but he was somebody I'll tell 552 00:21:34,379 --> 00:21:31,539 you that you just enjoy being around he 553 00:21:37,889 --> 00:21:34,389 just seemed like he's just a good coach 554 00:21:39,779 --> 00:21:37,899 good team leader excellent you know in 555 00:21:40,889 --> 00:21:39,789 terms of working with people they bring 556 00:21:42,749 --> 00:21:40,899 congressmen you know we've had 557 00:21:49,769 --> 00:21:42,759 presidents come here and he'd always be 558 00:21:55,259 --> 00:21:53,820 I think to me that the lunar landing has 559 00:21:57,810 --> 00:21:55,269 probably been one of the greatest things 560 00:21:59,869 --> 00:21:57,820 that man has ever done no question in 561 00:22:02,519 --> 00:21:59,879 terms of exploration it is the greatest 562 00:22:04,169 --> 00:22:02,529 but it took thousands and thousands and 563 00:22:06,029 --> 00:22:04,179 thousands people took a lot of money 564 00:22:07,379 --> 00:22:06,039 took a lot of blood and sweat people 565 00:22:09,419 --> 00:22:07,389 prepared to do that 566 00:22:11,700 --> 00:22:09,429 there was a lot of safety issues had to 567 00:22:13,919 --> 00:22:11,710 be addressed a lot of unknowns a lot of 568 00:22:14,690 --> 00:22:13,929 things that we did that we knew it was 569 00:22:18,479 --> 00:22:14,700 different 570 00:22:20,099 --> 00:22:18,489 so there's no question culmination of 571 00:22:22,649 --> 00:22:20,109 actually landing in and bringing them 572 00:22:25,079 --> 00:22:22,659 back was getting the bike safely and 573 00:22:26,700 --> 00:22:25,089 once we had splashdown and recovering 574 00:22:28,950 --> 00:22:26,710 all that and that was the time to time
