Seattle, WA Factoid
Planes, yes. Windows, no. Seattle is home to corporate giants Boeing and Microsoft, but only the aircraft manufacturer is available for tours. The public can wander through an airplane assembly plant so large that it makes even 747s look small. Bill Gates' Microsoft, on the other hand, is off-limits. You're free to drive through the Microsoft campus, but its museum is open only to employees, their families, and friends.
