See an avalanche airbag in simulated use. By deploying in just a few micro-seconds, this device reduces the specific gravity of the wearer / user relative to the snowpack around them, in the unlikely event of being trapped in an avalanche. It allows a skiier or winter adventurer to be possibly jetissoned to the top of the snow mass and thus be rescued based on a visual signal or then the AM/FM transmitters that it carries on it. A helicopter rescue is also possible, as the signals can be collected from the air, and the yellow colour of the airbag immediately attracts attention. It essentially reduces your density making you less likely to be buried by more dense snow. Chunni Lal Thakur demonstrates the use of the airbag that Roderick Mackenzie has developed for the use of his heli-skiiers
