People do stupid things without thinking, or through misunderstanding.
Years ago having trained troops on both the Puma and Chinook on the same day we had an incident. On the Chinook it was a case of only exit to the rear between the 4 and 8 o’clock. On the Puma it was only exit between the 10 and 2 o’clock……. Shortly afterwards I, on the Puma had a soldier follow the orders for the Chinook and ran straight back and under the tail rotor which sliced straight through the camouflage on his helmet, but luckily not his head. A taller man would have been hit.
Later on, we had a Major exit the aircraft at night from 150ft taking the vertical route down. I guess he didn’t mean to do that either.
