A jumbo jet was making its approach for landing in Seattle 
yesterday when an electrical malfunction disabled all of 
the aircraft's electronic navigation and communications 
equipment. Due to the clouds and haze, the pilot could 
not determine the jumbo jet's position and course to steer 
to the airport.

The pilot saw a tall building, flew toward it, circled, 
drew a handwritten sign, and held it in the plane's window. 
The pilot's sign said "WHERE AM I?" in large letters.

People in the tall building quickly responded to the aircraft, 
drew a large sign, and held it in a building window. Their 
sign said "YOU ARE IN AN AIRPLANE."

The pilot smiled, waved, looked at his map, determined the 
course to steer to SEATAC airport, and landed the plane safely.

After they were on the ground, the co-pilot asked the pilot 
how the "YOU ARE IN AN AIRPLANE" sign helped determine
plane's position.

The pilot responded "I knew that had to be the MICROSOFT 
building because, similar to their help-lines, they gave 
me a technically correct but completely useless answer."
