  • This is a good scene from the the movie, "The Right Stuff"

  • If memory serves, Grissom was vindicated when a research team recovered the Liberty Bell capsule from the bottom of the ocean. The detonator control was in the off position, and it had not been activated. Way to go Gus!

  • @twistedyogert When an aircraft approaches the speed of sound, the sound waves and pressure waves the aircraft creates build up in a single large pressure wave on the nose of the aircraft. When the aircraft surpasses the speed of sound, the plane flies through this high pressure wave. When the wave collapses on itself behind the plane it causes a loud boom. It is all because of pressure differential. It's the same thing that causes thunder and whip cracks.

  • Why are sonic booms produced?

  • Anyone know what the burn time on those rockets were.

  • Maravilhoso....showw...d+

  • @vicroc4 According to Yeagers memoirs Glennis was at home and "didnt hear about it before Chuck got home". But actually it wasn't even planned that the Sound Barrier should be broken on that day it just happened.

    As for Grissom yes some treated him with suspicion but the people who knew him never doubted him. Actually it caused his death because the hatch on Apollo 1 was designed to be difficult to open because of his mishap.

  • @ovemunk The boom occurred over Victorville, CA, and was apparently heard in that area. Glennis might not have been on base, but she likely knew about the plans to exceed the Mach - they'd been doing a long process of edging closer, exploring the transonic flight regime before actually breaking the Mach. Goodlin was testing the second XS-1 for Bell at the time, and might have been on base. As far as Grissom - it's taking some license, but he was treated as suspicious by the NASA IIB.

  • Yeah nice BUT - Yeagers wife didn't know he had broken the barrier before he came home that evening. NO visitors(Pancho Barnes) were allowed on the airfield, Slick Goodlin were gone at the time and nobody on the ground heard the sonic boom. Hollywood Hookum. Besides, the movie is GROSSLY unfair to the late Gus Grissom (who later was killed in the Apollo 1 fire). It portraits him as a whimp and is very close to slander. He DID have "The Right Stuff".

  • great video!!!
