A helicopter was flying over Seattle when an electrical short disabled all of its navigation and communications equipment. Due to the clouds and haze, the pilot could not determine the helicopter’s position and course 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. In large letter, the pilot’s sign read: “Where Am I?”
The people in the building quickly drew a large sign, and held it in the building’s window. Their sign read: “You Are In a Helicopter.”
The pilot smiled, waved, looked at his map, determined the course to SEATAC airport, and landed safely.
After they were on the ground, the co-pilot asked the pilot how he determined their position.
The pilot said, “I knew that had to be the Microsoft building, because they gave me a technically correct, but completely useless answer.”
