The army use to make us take the seats out, then put them all back in again...facing the other way for our trooping contracts.
Soldiers are all brave, so they didn't squeal when we rotated. Well, not many of them anyway. However, the spontaneous clutching of the armrests, did cause them to drop their armory. The cabin crew spent considerable time each flight, retrieving hand-grenades, rifles and daggers from the back of the cabin and returning them to the men.
Cries like "I had a
blue hand-grenade...
" took up a lot of extra time.
