What is the oldest Military Aircraft that you Operated, Jumped From, or Rode In as a Service Member?

As a young paratrooper, the first military aircraft that I jumped from was a Fairchild C-119 Flying Boxcar (a Berlin-Airlift era aircraft introduced in 1949). To tell you the truth, I am happy that it was my first jump aircraft, because I could actually see the rivets in the skin spinning around, as the engines revved up, and I was HAPPY to get out. Interestingly, the C-119 was known to have one of the highest rates of parachute malfunctions, believed to be because of the unique slipstream from the twin tailboom assembly. I think that the second-oldest that I jumped from was a U-6A Beaver that entered Service in 1952. I always wanted to jump from a C-47 Dakota, but that was reserved mostly for the True Heroes from WW2 and Korea.

But this isn't just for Paratroopers. If you were Crew, Paratroops, or Cargo, tell your experience.
