A blind pilot and co-pilot walk onto a plane. The pilot's cane is white and the co-pilot's guide dog walks beside him. The passengers look nervous but the plane takes off normally. It starts to go faster, heading for the end of the runway. Passengers start screaming. At the very last moment, the plane lifts off. In the cockpit, the pilot says to the co-pilot, 'You know, one of these days the passengers aren't going to scream and we're both gonna die.'
