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 and course to steer 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 said "YOU ARE IN A HELICOPTER."
The pilot smiled, waved, looked at his map, determined the course to steer to SEATAC airport, and landed
safely. After they were on the ground, the copilot asked the pilot how in the world the "YOU ARE IN A HELICOPTER"
sign helped him to determine their position.
The pilot responded, "I knew that had to be the Microsoft building because they gave me a technically
correct, but completely useless answer."
