Did you know that if Yeager had not done it on that day, Bob Hoover might have been the pilot flying the X-1 when it went past Mach 1.
Apparently, they alternated flights in the beast.
In fact, Yeager had cracked his ribs in a horse accident and shouldn't have been flying that day. He didn't let anyone know about the accident. If he had, Bob would probably have been flying that day instead.
As is was, Bob was flying chase plane behind Yeager that day.
Not to take away anything from either of them - I highly admire the accomplishments of both men.
I do miss seeing Bob flying that Shrike Commander doing aerobatics with both engines feathered. Also his P-51 routines. An amazing pilot.
