Practice Listening: Multiple Choice, Single Answer ID: #40087 Short Chuck Yeager
Instructions
In 1947, the aviator with the right stuff, Chuck Yeager, hopped aboard his EX1 and with a giant wound, broke the sound barrier. Over the next 21 years, the X series of experimental aircraft took test pilots higher and faster than they have ever flown, gathering data on the effects of altitude and speed at the edge of the Earth's atmosphere. By the time the last X15 aircraft flew its final run in 1968, the way was paved for another era of flight and for journeys across the atmospheric divide into space.

What was the significant achievement of Chuck Yeager in 1947?
