Only a few years ago, before I had completed my pilot's licence and rejoined society, I was crewing a Caribou on an airdrop sortie in SWBTA. The sortie involved a TAC flight to the DZ, followed by the drop and then a more 'leisurely' flight back to our airfeild. during the return flight, an army air despatcher was allowed to sit in the RHS while one of the pilots went back for something to eat. He ended up 'flying' the 'bou for about 20 minutes. Turning onto headings and holding about 1500AGL (but not touching the engines). Only on the last leg did the pilot take his seat again.
No names, no ROPs...
