"A helicopter was flying around above Seattle when a malfunction disabled all of its electronic navigation and communications equipment. The clouds were so thick that the pilot couldn’t tell where he was. Finally, the pilot saw a tall building, flew toward it, circled, and held up a handwritten sign that said WHERE AM I? in large letters. People in the tall building quickly responded to the aircraft, drawing their own large sign: YOU ARE IN A HELICOPTER. The pilot smiled, looked at his map, determined the route to Sea-Tac Airport, and landed safely. After they were on the ground, the copilot asked the pilot how he had done it. “I knew it had to be the Microsoft building,” he said, “because they gave me a technically correct but completely useless answer."
