A pilot is flying a small, single-engine, charter plane with a couple of really important execs on board into Sea-Tac airport. The fog is thick, the visibility is 40 feet, and his instruments are out. He circles looking for a landmark, and after an hour he is low on fuel and his passengers are pretty nervous. At last, through a small opening in the fog he sees a tall building with one guy working alone on the fifth floor. Circling, the pilot banks and shouts through his open window, "Hi, where am I?"

The solo office worker shouts "You're in an airplane". The pilot then executes a swift 275 degree turn and performs a perfect blind landing on Sea-Tac's runway, twenty five miles away. Just as the plane stops, the engine cough and die from lack of fuel. The stunned passengers ask the pilot "how did you do it?"

"Simple" he says. "I asked the guy in that building a simple question. The answer he gave me was 100% correct, but absolutely useless. Therefore, that must be Microsoft's support office and from there the airport is thirteen minutes away on a course of 187 degrees."
