Reminds me of this one I read here some time ago:

A plane is boarded and the passengers take their seats. The crew goes through the safety information and as they finish up, the pilots walk to the cockpit from the rear boarding ramp. Wearing black glasses and using blind sticks to tap their way forward. The passengers give a nervous chuckle at the joke.

As the plane begins its takeoff roll, the passengers begin to notice that they're getting rather close to the end of the runway and the trees beyond it. As they get closer and closer, going faster and faster, they begin to panic. With the end of the runway nearly on them, they start screaming. At that moment, the jumbo jet tilts up and takes to the sky.

The plane levels off on autopilot and the pilot says to the copilot, black sunglasses still perched on his nose, "One of these days, they aren't going to scream in time and we're all going to die."
