"when did grd trades become crew"
surely they beacme "crew" when they became ground crew. I don't think the aim of this thread is to discuss the airCREW and groundCREW divide, but its also not to widen it. GroundCREW are a huge and pivotal part of flying and without them we wouldn't be able to fly our aircraft. Comments like "when did grd trades become crew", I feel, are not appropriate.
