Chuck yeager

Chuck Yeager was an American general and a test pilot in the US air force. He entered pilot training in 1942 and became a p-51 pilot. He became a test pilot once Wold War 2 was over. He tested many different types of aircraft and rocket planes in his career as a test pilot but in 1947 he became the very first man to ever travel faster than Mach 1. His record was quickly broken by a man named Scott Crossfield but Chuck answered back, beating Scott's mach 2 with mach 2.4!

Two nights before Chucks test flight he fell off a horse and broke two ribs. He only told his wife and the man that closes the door on his plane, Mike Riddle. He was in such pain the day of the flight that he could not close the door of his aircraft and had to get Riddle to close it for him. Yeager broke the sound barrier on October 14, 1947 flying the experimental X-1 at mach 1 at an altitude of 45,000 feet, with two broken ribs...

I think that Chuck must have been quit a brave man to test out all of these new airplanes. He was the first man with the record and the third, because Scott beat his original record. He may have been a bit of a reckless man though because of his not telling anyone about of his broken ribs.
