"If air travel has lost its romance, get it back" at this museum near King County Airport, where a "glorious glass-walled" gallery houses a collection of "modern and vintage aircraft" ranked by some as "on a par with the Smithsonian's"; it's so "cool" you'll want to "plan several hours" to visit Boeing's original 1909 plant, "tour a Concorde", "sit in a couple of cockpits" or try one of the "fun flight simulators"; N.B. free from 5–9 PM on the first Thursday of each month.
