Video of the edge of space

At a local school, 3 Sixth Formers were sponsored by the Ogden Trust to send up a weather balloon carrying a box full of computer sensors. It included a video camera. The Youtube footage can be seen from the link below. You can see the balloon bursting as the air pressure outside becomes too low to resist. I love the fact that you can see the thickness of the atmosphere and the curve of the Earth. I met the students involved and was immensely impressed. They tell an amazing story of how they tracked the box to the top of a tree in Yorkshire, spotted it from a micro-light and climbed the tree to recover the camera. Congrats to all involved! http://www.youtube.com/watch?v=m9UB_ENmWwY
