  • where were u?

  • At the gate to get into Edwards Airforce Base. There's a little Airplane graveyard thingee. So suffice to say we knew the shuttle was coming, but were still scared shitless when it got there...

  • whats that music in the background? is it from a soundtrack?

  • Fifth Element...

  • The shuttle doesn't use its main engine at any time after the launch. And it doesn't use its OMS engine at any time after the deorbit burn. It also doesn't circle during and after the reentry, all it does is a bunch of S-turns to dissipate forward momentum.

  • Wow..... talk about misinformed.

see all

  • Pah, When I was a kid in Alamogordo c. 1960 F104's, etc would just fly low and blast the school or what ever was available. It was big and It was great. Sometimes a window broke but so what. That was all gone with in a few years:: "Environmentalists"

  • Double sonic boom all the way across the sky -sobs-!!!11!!!!!one!!

  • You hear 2 booms because you hear the bow wave (the front of the shuttle) and the tail wave (the rear of the shuttle) both front and back of the vehicle traveling at super sonic speeds create the atmospheric change in pressure that's why you have 2 booms.

  • @drgentlewolf One boom for the nose, one boom for the vertical tail assy. Shuttle has funny aerodynamics :-)

  • I guess the shuttle would be getting slower ,as it get close to the earth..(tthe air port)

    Why can we hear sonic boom ?

    I think that Sonic Boom is made when something gets much more faster than sound speed.

    And Why twice?? Boom No 1.Boom No2?

  • Whenever the shuttle needs to rotate. The RCS is tied to the OMS (e.g. there are RCS thrusters in the two rear OMS pods as well) and used in conjuntion with it or alone. Generally the OMS does the heavier pushing and the RCS does the finer rotation and/or linear translation (for example when docking at fractions of an inch per second).

  • @chorioretinitis When are the RCS thrusters used?

  • You couldn't be more wrong.

  • The loud double boom is in fact a sonic boom. There are two distinct booms because of the extra large verticle stabilizer (or so I hear).

    The Columbia accident was damage to the left leading wing edge RCC. There was basically a huge hole in the wing. Upon re-entry, the hot gases entered the wing and ultimately led to the vehicle breaking up.

    Space travel is anything but routine.

  • I just heard the Endevour re-enrty today here in palm Beach thought my house was hit by a garbage truck. GREAT VIDEO!
