A stormy flight aboard a Boeing 707, and off-duty airline stewardess is sitting next to a man in the grip of a white-knuckle fever as he watches, through his porthole, the aircraft’s wing bending and bouncing in the tempest. The stewardess tries to reassure him; she works in the industry and flies all the time, she tells him. There is nothing to worry about; the pilots have everything under control.
“Madam,” he replies, “I am a Boeing Engineer and we did not design this aircraft to do what it is doing.”
