Airborne Awesomosity

The Flame Barrier

One of the most fascinating things about aircraft is how quickly these machines progressed. The Wright Brothers made their first powered heavier-than-air flight in 1903. Chuck Yeager broke the sound barrier in 1947. The Germans sent the first man-made object into space during a V-2 test flight in 1944. The breakneck speed at which aircraft and, by extension, spacecraft were advancing began creating problems. Lightweight metals were not strong and were not heat resistant. In the days of subsonic and even up to Mach 2 or so, the heat generated by friction with the air was minimal. However, once we broke the sound barrier and sought to go faster and faster, the materials available became more and more unsuitable.
