What happens to the gas bag once it makes orbit? Am I correct in assuming

that

there will be a serious pressure differential between the interior and

exterior

of the bag? I'm thinking "World's Largest Baloon Goes POP!" ?????


Maybe they're going to stress the skin so that it pops open at the back end,
with the escaping gas supplying thrust.

Hey, good idea!

I am wondering about possibly using Hydrogen. At the extreme altitudes
considered, I'd think the flammability issue would be much less. And
Hydrogen is significantly more bouyant than Helium. Maybe a mix of the two?
