Sound Barrier

February 15, 2008

On October 14, 1947, Brigadier General Charles “Chuck” Yeager became the first human to ever break the sound barrier.

The aircraft that General Yeager flew was the Bell-X1 which he named after his wife. His X-1 was called “Glamorous Glennis.”

Sound is described as vibration that travels through an elastic medium as a wave

Speed of Sound - describes how much distance such a wave travels in a given amount of time. This can only be done in dry air with a temperature of 21 C or 70 F

The actual speed of sound is: 344m/s OR 1230km/h OR 770mph OR 1130ft/s

I found some amazing pictures of different aircraft actually breaking the sound barrier. ENJOY!!
