C- 0, PRACTICAL WORK INSIDE THE AIRCRAFT10-8. Time warnings, paratroop door safety checks, and door bundle ejection are events that commonly occur during each airdrop operation. Time warnings and door procedures are completed during each airdrop operation, but door bundles are not always ejected.10-9. The time warnings and door procedures are considered critical aspects of JM operations during all airdrop procedures. When the twenty-minute warning is given, JMs unbuckle their seat belts and stand up. They move to the rear of the aircraft, turn, and face the jumpers. (All time warnings begin and end at the shoulders with closed fists.) They extend both arms straight forward, extending and spreading the fingers and thumb of each hand.
