the airport. The Ambassador's impact cut the stationary Trident in half and severed the tailfin of another Trident parked next to it. While this made G-ARPT a complete write-off, the aircraft next to it, Trident 1C G-ARPI, was subsequently repaired and re-entered service. (The latter aircraft would be involved in the worst accident in BEA's history as well as the worst involving a Trident, in terms of fatalities, on 18 June 1972.) As at the time of the accident both Tridents were empty and not being attended to while parked on the airport ramp, no BEA passengers or staff were among the fatalities.World directory of airliner crashes (1960–1969), Denham, T., Patrick Stevens Ltd, Sparkford nr Yeovil, 1996, p. 85 On 2 October 1971, Flight 706, a Vickers Vanguard (G-APEC), crashed near Aarsele, Belgium, following a mid-air rupture of the rear pressure bulkhead due to severe, undetected corrosion. All 63 on board died. On 18 June 1972, Flight 548, a Hawker Siddeley Trident 1C (G-ARPI), the aircraft that had been repaired and returned to service after being struck by BKS Air Transport Ambassador G-AMAD at Heathrow on 3 July 1968, crashed two minutes after takeoff from Heathrow Airport, killing all 118 passengers and crew. The accident occurred close to the town of Staines, Middlesex. This was the worst accident in BEA's history as well as the worst involving a Trident, in terms of fatalities. It was also the worst on British soil until 1988. On 19 January 1973, Vickers Viscount 802 G-AOHI crashed into Ben More, Perthshire while on a test flight. All four people on board were killed. Liveries Late-1940s – early-1950s BEA's early liveries in the late-1940s to early-1950s mainly consisted of a bare metal finish with upper case, black British European Airways titles above the cabin windows on each side of the fuselage, the aircraft registration in bold, black capital letters on each side of the rear fuselage as well as on the underside of each wing, and a contemporary BEA logo on each side of the forward fuselage featuring a stylised wing and BEA in capital letters on each side of the nose. Additionally, Vikings featured a name given to individual aircraft in black capital letters each side of the nose. Early-1950s – late-1950s By the early-1950s, the bare metal finish on most BEA aircraft had evolved to incorporate a burgundy cheatline separated by two thin, white
