If he manages to do that without dying (unlikely)
Johnny nearly died first attempt (rocket blowout) and then he only managed sixty feet.
Well, this next flight will be harder - but the one he's supposedly building up to do (launch from a balloon - get high enough to *NOT* see the curvature of the Earth) will be impossible.
Once he's up over 100,000 feet - he won't be able to parachute out. The world record parachute jump was 135,000 feet - but that guy was wearing a full-on space suit and jumping from a STATIONARY balloon.
He won't be able to wait to jump from a more reasonable altitude because his rocket is pretty streamlined and will very soon be heading downwards at a thousand miles an hour - and parachuting at that speed is suicide.
Honestly - if he really wants to do this - all he has to do ("all"!) is to replicate that world record balloon jump. Float up to 100,000 feet - take the photograph - then jump/parachute back down again (or maybe just let a little gas out of the balloon and float gently back down...or maybe don't even go up with the balloon - just send a GoPro camera...or maybe just BELIEVE THE FRICKING VIDEOS from dozens of such experiments already done (which clearly show the Earth is round).
The steam-powered rocket is just an unnecessary encumbrance.
Unless, of course this is all just some huge publicity stunt...just maybe!
