And because the raft escape was not only an inspired solution, but looked like something that just might be plausible (and was proven to be so on an early episode of Mythbusters).
Yeah, no. That myth was busted
It is possible to jump from a disabled airplane and use an inflatable life raft to safely return to earth (as in Indiana Jones and the Temple of Doom)
Any attempt to use the raft failed due to the instability of the raft in freefall. It was possible to rig the raft as a parachute and land with minimal injuries, but this would not be possible to perform while jumping from a disabled aircraft.
Well yeah, obviously in the real world you'd need to strap yourself in first, but that doesn't seem to me THAT far off from the movie. They still showed the raft itself landing pretty damn softly in the end, which is probably more than most people would expect to happen.
