B.O.A.C. Proving Trials 1975
The BOAC Concorde proving flight of 26 July 1975 was operated by Concorde G-BOAC (204) from Bombay to Kuala Lumpur as part of pre-commercial route trials across Asia. Piloted by Captain B. J. Calvert, this flight formed part of efforts to evaluate long-haul operations, including routing, fuel efficiency, and airport handling under tropical conditions. The sector was significant for the proposed eastern extension of Concorde services toward Singapore and Australia. Covers carried on this flight are scarce and philatelically important, representing the transitional phase before the start of regular Concorde services in January 1976.

NIC
This cover was carried on the BOAC Concorde proving flight of 26 July 1975, flown from Bombay to Kuala Lumpur by Concorde G-BOAC (204) under the command of Captain B. J. Calvert. It forms part of the limited route-proving trials conducted to assess long-haul supersonic operations prior to commercial service. The cover is personally signed by Captain B. J. Calvert, the pilot of the flight, adding to its authenticity and desirability. The marking “Concorde 4” and the annotation “No. 2 of 3 flown” indicate its very limited carriage, enhancing its philatelic significance as an early experimental Concorde flight cover from the Asian sector.

15 August 1975: Singapore to Bombay
NIC
This cover was carried on the BOAC Concorde proving flight dated 15 August 1975, flown from Singapore to Bombay by Concorde G-BOAC (204) under the command of Captain B. J. Calvert. It forms part of the extended Asian route-proving programme conducted in July–August 1975 to evaluate long-haul supersonic operations prior to the introduction of regular Concorde services. The cover is personally signed by Captain B. J. Calvert, the pilot of the flight, adding to its authenticity and desirability. The “Concorde 4” cachet and the notation “No. 1 of 5 flown” indicate the very limited number of covers carried on this sector, making it a scarce and significant philatelic item representing early Concorde experimental operations in the Eastern network.
