"Helicopters and Microsoft" joke

A helicopter was flying around 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 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."
