BS,
We often had flights were there were no post-flight snags - like in Tehran, Nairobi, Ohakia, El Adem, Ankara, Gardemoen
Mind you we often seemed to need engine changes in Offut, don't know why.
Folklore had it that Eng Wg always put a bag o'nails up for the Rangers so that the crew and one crew chief could sort it out, do the work of 30 groundcrew, and get the chinagraph line ever upwards at no cost to Eng Wg, apart from the crew chief.
Sometimes the plan went tits up. I still remember one rather bemused sgt flown out to Offut to assist with an engine change - mere sgts never got that opportunity normally. Wonderful name for a sooty - Hammer
