I never saw a B-47 yet either. I simply have to make that trip to that museum in Ohio.
I was stationed at a base once that had a burned out hulk of a B-58 Hustler that the fire guys used to practice on. It was beautiful even in that state.
When I was over seas, back when Iran blew up in '79, I saw a weird looking air craft on the flight line that I actually had to ask the maintenance guys what it was. It was one of the last B-57 Canberras we still had operational in USAF. It was set up for reconnaissance or EW, I dont know which. But there is was sitting for a few days and then I never saw it again. An interesting Doc on the plane

Its my understanding they played a large role in the Indo/Paki conflicts.
