Thanks, Emmett.
Aircraft is an Air Force C-123 Provider -- a twin-engined baby brother to the ubiquitous C-130 Hercules that is still in service.
Had four flights, in them, while in Viet Nam. C-123s were the aircraft used to spray Agent Orange during Operation Ranch Hand. The squadron and aircraft used in the operation were located on the opposite side of the runway from my F-100 squadron, at Phan Rang. When my first load crew chief returned to the World his severe case of shoulder acne was diagnosed as caused by exposure to Agent Orange. So far, I don't have any symptoms of the 27 diseases the V. A. recognizes as Agent Orange caused.

I pretty sure the car is a Pontiac, though don't know the model nor year, but will guess about 1953.
