01/22/2007. Remarks by Jack McKillop: "This T-29A-CO navigator trainer was delivered to the USAF in December 1950. It was withdrawn from use in 1973 and used as a ground instructional trainer at Sheppard AFB to support aircraft maintenance training. The aircraft is now preserved at the Sheppard AFB Air Park in the markings of a MC-131A Samaritan."
