In 1967, Trans Meridian Air Cargo operated a number of flights with cattle out of Groningen Airport Eelde
in the Netherlands to Teheran in Iran. Trans Meridian Air Cargo operated their Douglas DC-7CF G-ATMF 'Sir Benjamin' on these flights.
As the titles Trans Meridian London on the aircraft suggest, the company operated out of London at that time.
Trans Meridian Flying Services was initially based at Liverpool and started operations with Douglas C-54B Skymaster G-ARXJ
on 1 November 1962. Early 1966, Trans Meridian moved to the London Luton Airport.
On 5 November 1956, Douglas DC-7C c/n 44873 l/n 656 was delivered to Pan American World Airways as N731PA “Clipper Bald Eagle”.
In 1959, the Douglas DC-7C “Seven Seas” N731PA was converted to a DC-7CF freighter. On 15 March 1965, the aircraft was sold to
Liberty Air Inc., Los Angeles, and on 29 June 1965 re-registered N7314. On 29 December 1965, registration N7314 was cancelled
as exported to England. On 30 December 1965, the DC-7CF was registered G-ATMF in the UK with Trans World Leasing, Luton. On 18
May 1967, the G-ATMF was registered with British Overseas Airways Corporation (BOAC), London. On 6 July 1967, the G-ATMF was
registered with Transmeridian Flying Service, Luton, later operating as Transmeridian Air Cargo, Southend-on-Sea. Douglas DC-7CF
G-ATMF was operated by Trans Meridian until it in March 1972 was withdrawn from use. On 13 April 1972, after the plane was sold
in France, registration G-ATMF was cancelled. The aircraft was purchased by Transports Aeriens Reunis and should be registered
as F-BTDJ in France, but the DC-7CF didn't enter service with Transports Aeriens Reunis and was finaly scrapped in Nice, France.
