A helicopter was flying around above Seattle yesterday 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 hand-written sign, and held it in the helicopter's window. The pilot's sign read "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, determined the course to steer to the Seattle-Tacoma airport, and landed safely.
After they were on the ground, the copilot 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, similar to their help-lines, they gave me a technically correct but completely useless answer."
