Boyd chose Yeager due to the young airman\u2019s keen mechanical ability and calm under pressure.\u00a0 Yeager was tapped to replace a man named Slick Goodlin, who had demanded too much money, as a civilian test pilot, to attempt the feat.\u00a0 Goodlin thus lost his chance at aviation immortality.<\/p>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\"

center;\"><em>Chuck Yeager and the location of Muroc Army Airfield<\/em><\/p>\n<p>Yeager was sent out to Edwards AFB, then known as Muroc Army Airfield.\u00a0 He began a series of flights in the Bell X-1.\u00a0 A bullet shaped plane that was built by the Bell Aircraft Company of Buffalo, New York.\u00a0 There were several test flights before the barrier was broken.\u00a0 One of the great technical difficulties was the fact that the pilot was unable to raise or lower the nose of the aircraft at speeds around .95 Mach.\u00a0 Apparently the shock wave removed the air from around the vertical stabilizer causing the issue.\u00a0 Jack Ridley, one of the engineers, cleverly fixed the problem.<\/p>\n<figure><img loading=\"lazy\" decoding=\"async\" class=\"alignright\" src=\"https:\/\/doctoraviation.com\/wp-content\/uploads\/2017\/10\/Bell-X-1-in-flight-black-and-white.jpg\" width=\"227\" height=\"137\" \/><\/figure>\n<p>How fast is Mach 1, (AKA the sound barrier, the speed of sound)?\u00a0 It is the speed of how quickly sound waves travel and at sea level it is around 760mph.\u00a0 However at the 40,000 foot level where Yeager was flying it is around 660 mph.\u00a0 Ironically, breaking the sound barrier was not planned the day Yeager accomplished the feat.\u00a0 He was supposed to go to around .97 Mach.\u00a0 Yet, while heading towards Victorville, CA the Bell X-1 accelerated more than anticipated and the first sonic boom was heard on the desert floor.\u00a0 The sound barrier was broken.<\/p>\n<figure><img loading=\"lazy\" decoding=\"async\"

classified for several months, keeping Yeager from notoriety.\u00a0 It was also kept secret that Yeager was flying with a couple of busted ribs on the flight.\u00a0 Breaks courtesy of a tumble off of a horse the prior weekend.<\/p>\n<p>This past week there were lots of celebrations of the event at Edwards AFB.\u00a0 You can see some brief footage of the original flight at the following
