NASA Aircraft Crash-Absorber Shield

I'd like to think the research we're doing is going to end up in airframes and will potentially save lives. We crash-tested the helicopter by suspending it about 35 feet (10.7 m) into the air using cables. Then, as it swung to the ground, we used pyrotechnics to remove the cables just before the helicopter hit so that it reacted like it would in a real accident.
