That brought back memories. I was a helicopter crew chief and we would always send the newbs off to find rotor wash whenever it was time to wash the helicopters. Usually send them over to the Air Force hanger and ask them for it. That or a bolt stretcher when installing rotor blades...Ah fun times.In the Mil world, I would often send young soldiers off looking for a roll of "flight line" when they became too bothersome... or a weapon repair tool called a "pair of T-R double E's.... this barrel just won't come off without it."
