I don't remember this number and unfortunately I didn't keep records, but I did fly several 63-xxxx birds except when I flew them they were pretty new (8 years old(?)). I flew out of McGuire, where were you stationed.
I am sure the oldest plane could have been a piper cub type or Cessna 140, some kind of side-by-side tail dragger (I was very young). Then came a Navy R5D (C-54) and then a T-37.
