Yep. Not only does it fly, they used to use them to deliver rocket parts from point A to point B.
Your pictures look like they gave them an engine upgrade to turbo-props. The original airframe (C-97) used radial (piston-popper) engines. I guess they needed them for the extra weight.
I hear that they're used today to ferry Micheal Moore around.
I had returned from a trip right before Christmas when the pilot came on the intercom: "Ladies and gentlemen, welcome to Seattle. When deplaning please remember to push and shove in your usual holiday fashion."
LOL!
