Sure, you have to pay $14 to get into the Museum of Flight. And then you must wait in a long line to pay another $8 for a ride in one of two X-10 flight simulators. But once you get into this shiny-white flying chariot, all cost-benefit doubts vanish. For three minutes, you're the pilot in a ridiculously armed fighter plane, blasting enemy installations on the ground while performing 360-degree loop de loops. Got a friend who owes you money? Strap him in as your co-pilot and hang that bitch upside down for what I guarantee feels like an eternity. And there you have it: more combat flying experience than the president of the United States ever racked up.—John Metcalfe 9404 E. Marginal Way S., 764-5720, www.museumofflight.org.
