I watch it almost every day, it's fascinating. There's one series "Learning to Fly" which follows a student pilot through her training, right now there's a show about this guy building his own aircraft. Yesterday there was an awesome show about the Boeing 777. They showed the wings being tested to failure, they held the fuselage down with 500,000 lbs force and applied a million pounds at the wingtip until it broke. The wingtip ended up 25' higher than its starting point before the wing broke midway.
