"Lost Helicopter" joke
A helicopter was flying around above Seattle yesterday when an electrical malfunction disabled all of the aircraft`s electronic navigation and communication equipment. Due to the clouds and haze the pilot could not determine his position or 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 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 and determined the course to steer to SEATAC (Seattle/Tacoma) 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 they gave me a technically correct but completely useless reply.
