I still can't believe the space shuttle is still in operation. I remember being 13 years old in 1974 when I built a space shuttle model rocket and would shoot it off around the neighborhood. It had a plastic tube that you could put a snake or lizard in (well we did) and shot it off and the speed of sound. Sorry to so the snake did not make it! Now 37 years later it's the second to the last space shuttle launch.  A true test of NASA's engineering. Check out his video from an airplane capturing the space shuttle endeavours last launch! Very Cool!
