No prob on the connection. Yes on the gate check of bags.
Superb museum at W-P. ^ ^ They have one of the last remaining XB-70's supersonic bomber. We only made 3 of them, one crashed into a photo-chase plane. Where's the third one??
Be sure to put the Udvar-Hazy branch of the Smithsonian's National Air & Space Museum (at IAD):-: :-: on your list of fantastic places to visit. They have the prototype Boeing 707, whose test pilot flew a slow roll at a Seattle airshow, over a group of potential buyers.

Boeing management was apoplectic, but the buyers loved it, and bought 707's! They also have the Rockwell Space Shuttle Enterprise, and the B-36 Enola Gay. I was priveleged to sit in the cockpit of Enola Gay when she was at Silver Hill. She saved my uncle's life. In 1945, he was a 19 year old Navy landing Craft coxwain, slated for the first wave to invade the Japanese homeland. He'd of been toast. Cannonfodder.
