09/30/2009. Remarks by Johan Visschedijk: "Registered to Channel Airways as G-AVYC on November 13, 1967, this aircraft was produced as a Trident 1E-140 with a high-density seating of 139 passengers. However, it was never delivered to the airline, instead the registration was transferred to Hawker Siddeley on November 13, 1968, and subsequently converted to a Trident 1E-110 with a low-density seating of 115 passengers.

In 1967 the shareholdings of British European Airways (BEA) in Cambrian Airways (33.33%) and BKS Air Transport (30%) were transferred to a new BEA subsidiary company, British Air Services (BAS), which looked after the affairs of the two airlines. BAS was 70% owned by BEA and the balance by the individual stockholders of Cambrian and BKS.

G-AVYC was delivered to BAS in February 1969 and operated by BKS, hence the 'British Air Services' titles and the 'BKS' logo on the aircraft. On October 31, 1970, BKS became a wholly owned subsidiary of BEA and the name was changed to Northeast. On March 31, 1974, BEA, Cambrian and Northeast, together with British Overseas Airways Corporation (BOAC) merged into British Airways (BA). G-AVYC was eventually withdrawn from service on July 31, 1980, and was broken up in May 1981."
