Convair T-29 Flying Classroom R4Y/C-131 Samaritan & CC-109 Cosmopolitan

The T-29/C-131 series of aircraft was one of the military's many cost-saving examples of purchasing existing civil and commercial designs for their utility and transport needs. The first military Conviar-Liner was accepted on March 8, 1950. Military production eventually eclipsed civil production with the last Convair-Liner built being a military Canadair CL-66B, which was delivered on March 3, 1961. This aircraft was the last of 568 military Convair-Liners built.
