A pilot is flying a small single engine plane with a lot of really important execs on board into Seattle airport. There is fog so thick that visibility is 10m, and his instruments are out. He circles looking for a landmark and after an hour, he is low on fuel and his passengers are very 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 solitary office worker replies: "You're in an airplane."
The pilot executes a swift 275 degree turn and executes a perfect blind landing on the runway five miles away. Just as the plane stops, the engines cough and die from lack of fuel. The stunned passengers asked the pilot how he did it.
"Simple," replies the pilot, "I asked the guy in that building a simple question. The answer he gave me was 100 percent correct but absolutely useless; therefore, that must be Microsoft's support office, and from there, the airport is just 5 miles away on a bearing of 87 degrees!"
