A Seattle business executive needs to go to Portland, so he drives from
downtown Seattle to the airport. He gets into a helicopter, and the pilot
flies up into the clouds. Then a terrible thunderstorm begins. Lightning
hits the helicopter, knocking out the radio and all the navigational
devices. The pilot doesn’t know where he is or which way to go, but he goes
down out of the clouds and sees a tall building. He holds up a sign saying:
“Where am I?” The people inside hold up a sign answering: “In a helicopter.”
Then the pilot flies directly back to the airport.
After landing, while walking down the runway, the executive says: “That
was amazing. How did you find your way back here?” “I knew that must be the
Microsoft building,” the pilot responds, “because the answer was technically
correct–but for all practical matters, useless.”
