Okay....here's another one. Did you know that when the sound barrier is broken, you can actually see it bend the air?
When I worked at Pan Am, the Concorde SST jets with British Airways and Air France were taken out of service in 2003 because of an accident that killed many people. Most of these supersonic aircraft (7 with BA and 7 with AF) had to fly back to their base (London and Paris). BA offered PA employees in Miami and New York an opportunity to fly on the Concorde back to London. It was just the crew up front and anyone who had the time and the wherewithal to fly to London as a non-revenue passenger. The schedule worked out well because once we would arrive in London, a Pan Am flight was returning to Miami about 90 minutes later.
I went home, grabbed my passport, kissed my wife and told her I'd be back in the morning; I was flying to London. I couldn't explain any more than that. No luggage. Just me and my documentation. There were about 15 of us ready to go. The first thing we noticed was that the interior of the aircraft was very cramped. It looked like we were walking into a dart. Think of a public bus and you've got the right idea. Windows were very small. Once we took off, we had to fly over the Atlantic a short distance and climb to 50,000 feet (20,000 more than most commercial jets). You could actually see stars in the sky during the daytime. The Concorde increased speed and attained Mach 1 ... the speed of sound. The pilot went on the intercom and told us to look out the window toward the front of the aircraft. When we broke the sound barrier, it literally looked like we were punching through a piece of clear plastic wrap. (see the video and you can tell how that looked in the air.) Another thing to also note is the fact when the plane approached Mach 2, even though the outside air was very thin, the friction through the air at that speed caused a lot of heat on the body of the SST. Heat makes things expand. So it was true with the Concorde. The Concorde expanded, nose to tail, 10 inches in length and the special paint on the fuselage helped keep the plane cooler. You could still feel the warmth on the window though. Air temperature at that height is approximately 70o BELOW zero.
I had about the same room inside my AMC Pacer than they've got in this cockpit. Can't even stand up straight.
