Helicoptor Story !

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.The pilot saw a tall building, flew towards it, circled, and held up a handwritten sign in large letters - "WHERE AM I?"

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

The pilot smiled, waved, looked at his map, found his directions, and flew to Seattle airport safely.

The co-pilot asked "How did you manage to find your way?".
Pilot said "I knew that tall building had to be MICROSOFT, because they gave me an answer that was technically correct but completely useless"
