The problem is nothing experimental is flown without a chase plane or
two. You should see conventional contrails along with that produced by
the experimental airplane. Generally new engines are put in
conventional aircraft, often as only one of a few engines since you
don't trust the new beast. Now if the engine is debugged and has a
corresponding project, I suppose they could be flying a plane, but
there would still be chase.

what kinda chase  set-up would they use for a pulse jet UAV
traveling  across nevada  out to sea  at about 5500 mph  at 85k+
altitude  ?  maybe a blackbird or ??   dunno what we have that could
shadow that kinda test ?   maybe station planes all along the flight
path   watch it  or use a satellite to track it ?   it's probably hard
to find enough space and places to performance test that kind of
vehicle .

Oh, now it's both loud and fast?

ye ha doggie  .....!!!

 it's like  chain thunder /  series sonic booms.   it's  very
attention getting .   fast ? ......... I did say you only have "
moments " to  look  for  it before it's gone.  I've seen missiles that
didn't seem to disappear that fast ( course they were going " up " and
not across )  .  you notice the  sonic booms  sound , it rises up a
bit and then very suddenly ( way sooner than you expect )  it tails
off to nothing .......  you're not even sure where it came from ....
just , generally, the direction it went . 


it's the actual point of my first post .  THIS thing is probably
faster than anything you have seen before and makes sounds like you've
never heard as well.   at least , I've never heard anything like it
before .  never saw a doughnuts on a string  con trail ...... never
saw anything at all ...... my best guess  is it was  too high and
WAY ahead of the sound it was making  or I couldn't keep up with it as
it passed.    never saw hide or hair of it ....  but you sure knew it
was  up there .   it's pretty much the same experience with the other
people that  hear it.   I've heard it go " out "  ( due west )  twice
but never " back " .   same with the people  over in California
.... they've heard it several times , always heading west  !
usually at about 2 - 3 in the morning  ! 


the 5500 miles per hour  is  from the info  in the link  someone else
posted in this thread  ( mach 6 or 7 , I forget .. )  for the pulse
jet 

and the 85k alt ..... is partially from  you ( you said they couldn't
legally fly it under 65k  )   ......... add the sonic boom front and
it'd  prolly need to be  at least 20k or better higher not to mess
with  commercial carriers .........
