Passengers on a plane notice that the pilot and copilot boarding the plane seem blind — both with dark sunglasses and using tapping walking sticks for guidance. Though nervous at first, they assume it must be some sort of practical joke.
As the plane begins to take off, the passengers see the end of the runway rapidly approaching but the plane is still speeding on the ground.
Panicked, they scream loudly just before the end of the runway — right before the plane lifts off. They’re a little upset, but relieved that the pilots aren’t really blind.
In the cockpit, the pilot turned to his copilot and remarked:
“You know, Lou, one of these days they’re not going to scream in time, and then we’ll be in real trouble!”
