A pilot and a copilot are getting ready to land their plane on an exotic foreign runway on a foggy day
The pilot says “I’ve heard that this runway is pretty short, so why don’t you go ahead and give me quarter flaps, so we can slow this plane down. The copilot acknowledges, and gives quarter flaps.
As they begin to see the runway through the fog, they start to see how short the runway is. The pilot nervously says “This runway is shorter than I thought! Give me half flaps, we’ve got to slow this plane down! The copilot, also nervous, gives him half flaps.
The pilot, beginning to see the runway more clearly now through the fog, starts to panic at how short the runway is. “Give me three quarter flaps!” He shouts. The copilot gives him three quarter flaps as fast as he can.
All of a sudden, just as they are about to land, the fog breaks and they can see just how short the runway is. The pilot screams at his copilot “My god this runway is short! Give me full flaps, or we’ll crash! The copilot gives full flaps at blinding speed, while sweating more than he ever has in his life.
They careen towards the runway, and as soon as they touch down, they slow to a complete stop before the plane can roll off the other side of the runway. “Wow” says the pilot. “This runway is shorter than our plane is!”
“Yeah” says the copilot. “But it sure is wide!”
