The Argosy 650 

  

 

 

 

 

Design of the second aircraft type to bear the name "Argosy" was commenced in September 1956, following intensive, market research into freighting conditions all over the world. 

 

Various submissions for a Military transport aircraft had previously been made to the Ministry of Aviation without a resulting order, and the decision to go ahead on Company funds was particularly outstanding.

 

First flight with Mr. E.G. Franklin at the controls took place in January, 1959.

Eventually seven aircraft were ordered by Riddle Airlines, the first of which was delivered in December 1960 with A.R.B. and F.A.A. certification, and were soon operating on the Logair freight routes across the U.S.A. 
 
Three aircraft were taken by B.E.A. and used extensively until 1965, when they decided to replace them with five Argosy 650 Series 222.  These were developed from the earlier pattern to incorporate modern features such as fail safe wings, integral fuel tanks and wider doors to permit use of 108 in. wide pallets. 

 

Meanwhile, the aircraft delivered to Riddle were transferred to Capitol (5) and Zantop (2) Airlines, and continued their Logair operations.
