At 42,000' in approximately level flight, a third cylinder was turned on. Acceleration was rapid and speed increased to .98 Mach. The needle of the machmeter fluctuated at this reading momentarily, then passed off the scale. Assuming that the off-scale reading remained linear, it is estimated that 1.05 Mach was attained at this time.
Chuck YeagerThere is no kind of ultimate goal to do something twice as good as anyone else can. It's just to do the job as best you can. If it turns out good, fine. If it doesn't, that's the way it goes.

Chuck YeagerI ran the astronaut school for six years, and I was the commandant and when I finished in '65, 26 of my guys went into space as NASA astronauts that I trained.
