Abstract
Inflatable collars (32,34) are positioned on each side of a downed aircraft (10) and the collars (32,34) are connected by belly bands (80,100) to support the ends (18,20) of the aircraft (10). The bands (80,100) are positioned by positioning straps (90,90') which are attached to the aircraft (10) prior to inflation. The collars (32,34) are also attached to the aircraft (10) at intermediate locations (24,26). The collars (32,34) are divided into separate chambers (44,48,52,54,56,44',48',52',54',56') so that after inflation the different chambers of the collars (32,34) support the different parts (18,20,22) of the aircraft (10).
