They used to have a DC-2, I believe, that flew out of Long Beach. I heard it was an FAA bird. I haven't seen it in quite a while.
When I was applying to pilot training for the Navy, they flew me from Pensacola to New Orleans for a flight physical in an R5D (C-54) which wallowed, vibrated, and rattled. It was an experience. It turned out that the Flight Surgeon forgot to sign my physical so I had to retake it, this time at Pensacola Navel Air Station. By that time the AF accepted me and I signed up. A couple of weeks later I was accepted into the Navy flight program, but too late. Worked out good for me.
