Chuck Yeager broke the sound barrier 65 years ago, and last Sunday, he did it again, in celebration of the anniversary.

Sixty-five years ago, Chuck Yeager became the first man to break the sound barrier. At 24 years old, Yeager flew the experimental Bell X-1 jet plane to the record books. The X-1 was slightly shy of 31 feet long with a 28 foot wingspan, and hit 700 miles per hour, or mach 1.06, on October 14th 1947. The flight carried him to 43,000 feet and ushered in the era or supersonic aviation.

Ret. Brigadier General Chuck Yeager

Yeager's flight in the X-1 was one of the first steps of innovation in a field that would eventually lead to the pursuit of space flight and turn us into a space faring civilization. The flight has been covered in movies, books and documentaries, and now, the 89-year old former test pilot and air force brigadier general has celebrated the anniversary of the event. By flying in the backseat of an F-15 Eagle at Nellis Airforce base, Yeager once more broke the  sound barrier, reaching mach 1.4.

"Cockpits don't change; you just use the controls to make the airplane do what you want to do," he said with a smirk in an interview with the associated press.
