There was a hotel outside of Dodgeville, Wisconsin, that had a C-97 parked in front of it for years. Anyone could go inside, it was just open to the public. Had the same engines and wing as as the B-29 Super Fortress. Different body. It was NOT a KC-97, because it had no provisions for air-to-air refueling. Pure cargo.
That thing was a WHALE inside. Double decker. And the cockpit, nav, and engineer's station were mind blowing. All the guages, dials, levers, etc. where still in it. Even it's radar. Got pictures somewhere. Had to be at least 12 years ago, last I saw it, since my kids were small. Don't know if the plane is still there.
