Our young sons are airplane nuts and they get excited every time we drive in the parking lot for the Museum of Flight. It has a great interactive area for the youngest kids once they get tired of walking around oohing and ahhing over the huge and impressive aircraft over and around the whole place. But my favorite area is the relatively new Personal Courage wing, dedicated to World War I and World War II era flight. If you plan on going more than once, buy a membership -- it's a great bargain and you'll save 15% on all museum shop purchases.
