You Are in a Helicopter
Reader's Digest, Contributed by Linda A. Tozer, August, 1997, p. 26
A helicopter was flying toward Seattle when an electrical malfunction disabled all the aircraft's navigation and communications equipment. Due to the extreme haze that day, the pilot now had no way of determining the course to the airport. All he could make out was a tall building nearby, so he moved closer to it, quickly wrote out a large sign reading "Where am I?" and held it in the chopper's window.
Responding quickly, the people in the building penned a large sign of their own. It read: "You are in a helicopter." The pilot smiled, and within minutes he landed safely at the airport. After they were on the ground, the co-pilot asked how the sign helped him determine their position.
"I knew it had to be the Microsoft building," the pilot replied, "because like any computer company's help staff, they gave me a technically correct but completely useless answer."
