Jogging memory cells here, Corrosion. I recall one very windy day in Amsterdam. We got the pax off OK, but the wind increased to the degree that we couldn't open the cabin doors. In fact, 747s were being blown sideways on the apron. I needed to get to ops, and that hatch to the bay below the flight deck was the answer. I doubt I'm agile enough now. I last flew the type in July '92. Gosh, is it really over 27 years?
