Before I read anymore... I was guessing (educated) that since I saw somewnere that
1 - it was set up for "neutral bouyancy" and
2 - that they were very worried to control the amount of H2 used that it was filled only to the point where it would reach a specific pressure-altitude and stay there.
3 - The balloon concern seemed to be UV destroying the latex, not over pressure.
4 - Some high altitude balloons have been open bottom to eliminate the over pressure problem.
That... over pressure bursting was not a big worry.
Well see it I'm correct...
And, yes that web site appears to be an after-the-fact sort of thing only. Too bad. They should (yea, easy to say) have a media guy on a camera and web updates...
