"Microsoft Help-Lines" joke

A helicopter was flying around above 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 helicopter`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
helicopter`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 A HELICOPTER."
The pilot smiled, waved, looked at his map, determined
the course to steer to SEATAC airport, and landed safely.
After they were on the ground, the co-pilot asked the
pilot how the "YOU ARE IN A HELICOPTER"
sign helped determine their 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."
