Rock-Face Airbags

I have taken a keen interest in the recent Mars explorations, by both the UK and the US. Although the UK probe never returned any data, I still believe it is "alive".

Space exploratory probes have, since 1997, taken on a new form of planetary decent. Airbags play a very important part in absorbing much of the impact when landing. It's not too large a leap of thinking to assume the same could be used by us.

I'm not saying parachuter’s should start jumping out of planes with a few air-bags strapped to them.

I believe the technology of space probes could be used to help protect a certain demographic of society from accidental death from relatively large falls. Such people would include rock-climbers.
Upon freefall, away from a rock face, the airbags would calculate the rate of descent and also the approximate distance from sea-level where the user last zeroed the altimeter. Once an unacceptable rate of descent was reached along with a low enough altitude; the airbags would deploy, encompassing the climber in a protective bubble, thus assuming that the rope/holds had failed.
