Nitpick re "edge of space": Low earth orbit starts at around 160 km and orbits decay rapidly below 200 km. This is 36 km altitude. But what I think most people miss is that to "be in space" the way most people think about space you'll need to enter orbit which means that once you get up to 160+ km altitude you need to go sideways at roughly 24 times the speed of sound - and then you're in orbit. Then when you're all done having your fun you need to take all that orbital energy and do something with it. The best idea so far is to use it to burn up a heat shield. This business of going vertical a little higher than jets and a lot lower than satellites is a little pretentious. But it's fun and it's Red Bull so who cares!!
