If it's PICs vs ARM vs AVR
Then surely the arduino board is the way to go. It's open source, so it's got an IT angle.

Haven't really been following so if this has been said before, everyone please berate me.
You mention some kind of syringe-based mechanism. How about this: attach the plane to the plunger of a 100ml syringe and attach the barrel to the ballon. Suck 1ml air into the syring on the ground (at 100kPa). At 100,000ft (about 1kPa according to http://www.engineeringtoolbox.com/air-altitude-pressure-d_462.html), the plunger will fall out.
