The lost chopper pilot

A helicopter was flying around above Seattle when an electrical malfunction disabled all of the aircraft’s electronic navigation and communications equipment. Due to the clouds and haze, the pilot could not determine the helicopter’s position, or the course needed to fly to the airport.

The pilot saw a tall building, flew toward it, circled, drew a handwritten sign, and held it in the helicopter’s window. The pilot’s sign said “WHERE AM I?” in large letters.

People in the tall building quickly responded to the aircraft, drew a large sign, and held it in a building window. Their sign read “YOU ARE IN A HELICOPTER.”

The pilot smiled, waved, looked at his map, flew directly to SEATAC airport, and landed safely.

After they were on the ground, the co-pilot asked the pilot how the “YOU ARE IN A HELICOPTER” sign helped determine their position?

The pilot responded, “I knew that had to be the Microsoft building because the answer they gave me was technically correct but completely useless.”
