Mach 1.1
1.2
[inaudible]...Copy 1 minute
So 1 minute [til wave] point, 2 minutes til the boom.
Currently joins Mach 1.22
[inaudible]
Boom sound
[inaudible]
So one reason we started at 29,000 feet is the aircraft has a limit of 50,000 feet
and of that we have to use the pressure suit [inaudible] so we start from the highest possible,
dive down using gravity to help accelerate the plane [inaudible] supersonic in a small area and
by having it really steep we're really increasing the distance the shock is traveled. The further
we travel and then start to reduce. We're trying to keep the loud booms way off
to the middle of the lakebed there or the unoccupied desert first attempt.
Pilot radio talking ... 3, 2, 1
Ok 90 seconds to go [should be the boom]
Now you can see descending and you can see the glint as he's rolling over upside down and right side up.
Ok, he's supersonic right now.
Getting at 40,000 feet as he starts to pull up.
In this area we have a restriction being subsonic below 30,000 feet
Ok so the booms we're gonna hear have been generated
and they're making their way downhill
Pilot speaking [1.09 Mach at 40,000]
Copy 1.09 Mach
Boom sound and smaller boom sound
Pilot speaking: 1.08 Mach
Softer boom
[Inaudible...464 copy that 22 [inaudible] two, niner, eight, niner.
[Inaudible] ... descent [inaudible].
Here he comes over the tall building.
Jet sound
[Inaudible, people talking in the background]
