Two Pilots board airliner with dark glasses and white canes, in spite of the growing concern from the passengers, they duly line up on the runway and throttle up, the jet rolls faster and faster toward the end of the runway, the passengers sense disaster! They start to scream in mortal terror.... and the jet lifts off at the last second with a few feet of runway to spare... on the flight deck, one blind pilot drawls to the other, "Y'know Tim, one day they ain't gonna scream, and we're all gonna die!"
