We interviewed a number of the survivors from flight UA811. A United Airlines 747-200 that had suffered an explosive decompression at 22000 ft on 24th Feb 1989.
The shock wave from the decompression burst a number of the passengers eardrums especially in the lower first class cabin.
A number also suffered damage to their teeth as airpockets in fillings expanded. some passengers also ingested insulation material an other airborne particles.
The cabin also filled with mist.
Cant recall anyone actually saying they froze but maybe the sudden adrenalin rush of having an aircraft fall apart around you helps to keep the cold at bay.
