Every time I go, it feels like the first time. What a great museum we have here right in our own backyard (well, for those of you living in the Pacific Northwest that is). My favorite all-time plane (and I have a lot of favorites) has to be the SR-71 Blackbird. The only plane humans have ever developed that was fully functional and one you could picture Darth Vader flying as his prefered mode of transportation.
Here's the Old Man straddling the cockpit in what can only be described as the only time I could ever be photographed in the cockpit of an SR-71 Blackbird wearing a t-shirt and Seahawks baseball cap.
(For you aviation nuts the real pilots wore astronaut suits).
