PHX4 Rocket launches to over 200000' attaining the highest amateur two stage flight. (15 min 55 sec)

Took a while to show up in the lion kingdom's gootube recommendations. 46 miles is pretty huge for a private individual working with a few friends & a truck. In 4 miles, he's at the scientific definition of space which is rapidly becoming 50 miles.

Very conspicuous how the rocket was never photographed & the design was never revealed. The internet guessed various commercially available motor sizes. The only design clue is a long ramp for lifting off. He's well within ICBM territory & either didn't want it used by terrorists or was banned by ITAR. The terrorism danger is going to keep amateurs from sharing plans & getting into space for some time.
