Breaking the sound barrier with one's body sounds a bit dicey.
Well, it's not like I have anything important to say.
Yeah. You're talking to yourself and then all of a sudden you can't listen anymore...
Weather balloons keep rising until the falling air pressure makes the balloons expand to the point of disintegration (at about 40km altitude). Perhaps a similar thing would happen with this balloon. It still wouldn't solve the problem of being stuck in the capsule though.I like the note about how his parachute would have been set to automatically open at a certain altitude if for some reason he passed out during the fall, yet there was no mechanism to eject him from the capsule if he passed out during the ascent...
I wonder how long it would take for the helium to dissipate (if it would dissipate at all thru whatever balloon material he's using)... If it didn't dissipate... would he be floating for a really long time?
