More specifically, somewhere in this forum are images of a massive airship assembled by the Scottish contingent of BLAMers
Yep, that's the one I had in mind, though I've not found it yet; and I'm probably the one that included a link in the 'nef sticky, somewhere.
As I recall, much of the bag was from cereal boxes.
Woof!
as to helium vs Hydrogen - Hydrogen is safe enough, the Hindenburg catastrophe was a very small chance and it was media inflated. Noone counted how many planes dropped from the sky afterwards as long as the airplane industry was flourishing.....
AND, while still a bit causally controversial, I think the fabric doped with partial rocket fuel (powdered aluminum) is a bit suggestive.

Though it might have worked with a rigid frame airship (Zeppelin) instead of just a blimp.
Have to suggest the frame already present WAS the problem; shattered frame as projectiles into the bags would have downed a dig almost a surely. The bag and the rest of the frame DID descend slowly.
By the way, the subtext appears to me to include a bit of Brit-bashing. Sorry to our friends on the far side of the pond.
