Delivered as a Convair 440 to Swissair as HB-IMC in June 1956. Bought by Martinair in October 1966 and converted to CV640 in February 1967. Sold as N640R in September 1971. Seen taxying away from Schiphol Oost.

The extra length made the 640 a little sleeker looking than the CV-600, but both models, although not as successful as the 580, extended the useful life of the design.

The second of two Convair 640s that were originally delivered to the Arabian American Oil Company in 1952. Both Convairs were bought from Pacific Western Airlines in 1976, and both went to Wright Airlines in 1982.

Inspired by reading Martinair's early history in Propliner, I decided to squeeze what quality I could out of this slide, one of my first ever (and unfortunately not Kodachrome). A familiar sight at Southend after conversion from Cv-340 in 4.66, it's good to see she was still alive and well, stored by C&M Airways at El Paso as N640CM in the late 2000s

The Dart-powered Convairs were always a relatively rare sight compared to their Allison sisters. This one was originally CV-340 N727A with American Arab Oil in 1952, converted to 440 for General Dynamics (N7362) and then 640 in 5.66. Bought by PWA 5.67; to Wright 11.82 becoming N860FW. Later operated by Viking,Kitty Hawk and Rhoades among others; stored at Fort Worth - Meacham from 2000, fuselage only noted 2013

Whilst this aircraft is untitled, it does carry the Worldways logo on the fin.

This Convair rolled out as a 340 on August 19, 1953 for National Airlines (N8412H). Sold to Hawaiian Airlines in May 1959, it was re-registered N5514K and converted to a 640. Coming to Canada as CF-PWY for Pacific Western Airlines December 19, 1969, it went to Aero Trades Western in 1978 as PW standardized on 737s for passenger services. When Aero Trades ceased operations in 1984, the Convair went to Time Air until stored at Spring Bank, Alberta at the end of 1991.

Delivered to Lufthansa as CV440 D-ACUM in March 1957. To Air Algerie in June 1968 as 7T-VAO and converted to CV640.

Looking totally immaculate here with C-FPWY in the background, this Dart-powered Convair was converted from ANA CV-440 JA5055 in 12.65 and flew with Hawaiian as N45004 till sold to Pacific Western in 2.67. Wfu at Springbank, AB 12.91 and b/u 2.05
