A pilot is flying a small, single-engine charter plane en route to Seattle
with a couple of very important executives on board, when he runs into
trouble. Outside, there is a fog so thick that visibility is less than a
mile, and his instrument panel is malfunctioning. Unable to find the airport,
he circles the city looking  for a landmark. 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:

"Hey buddy, exactly where am I?"
The solitary office worker replies: "You're in an airplane."

Upon hearing this, the pilot instantly banks into a 275 degree turn and
executes a perfect blind landing on the airport runway five miles away. Just
as the plane stops, the engines cough and die from lack of fuel. The stunned
passengers ask 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, I knew that it must be Microsoft's Support Office. From
there, the airport is just 5 miles away on a bearing of 87 degrees!"
