Having met Mr. Yeager on a couple of occasions and heard hm talk on his flying exploits I am convinced of one thing irrespective of who was first through Mach 1. Even at his advanced age he has the biggest ego of any pilot I have ever encountered. That he had a fair degree of "the Right Stuff" is not in question. I just find his attitude rather unpalatable.
On the other hand Bob Hoover is one of natures gentlemen and truly a master aviator in all aspects of his flying over the past six decades.
