Comment I've got an idea !! (Score 1) 248
Seeing this and pondering about this problem, I suddenly came up with a terrific idea, for which I'll file a patent as soon as possible.
The basic idea, without revealing too much detail, would be to store some sort of very large sheet of tissue, or some other strong fabric, inside a pack or something. The sheet -- which could be duplicated as needed, to improve safety, let's say three of them -- would be neatly folded in order: 1/ to be stored efficiently and 2/ to deploy quickly and as widely as possible.
At some point in the reentry, let's say a few miles above the landing spot, the sheets would deploy thanks to a system of sorts -- let's say an altimeter -- and, by the magic of fluid mechanics and the Archimedes principle, would slow the rocket enough for it to land safely.
Now that I think of it, that system could be extended to people, who could jump from an airplane, just for fun or for military operations. Hmmm...
