And when you stand at the tip of a B-52 wing and see the long distance to the fuselage, and you look up and see those prodigiously sized ailerons over your head, you realize what a feat of engineering the plane is and was, notwithstanding.
There's a demo I do for students: you grab the tip wheel of an unfueled B-52 and give it a good hard lift. The wing will start bouncing and, if you keep it up, start to exhibit some complex flexure modes -- a sort of standing wave. The tip will eventually bounce with an amplitude of a couple of feet, just from muscle power. "Your job," I tell them, "is to understand in every way how something like this can be built and fly. I've just set several tons of aluminum into complex motion with my bare hands, yet it will provide lift and strength for several tons of fuel, several tons of bombs, and several tons of airframe."
