On 5 January 1960, Vickers Viscount 701 G-AMNY was damaged beyond economic repair at Luqa Airport, Malta, when it departed the runway after landing following a loss of hydraulic pressure.

On 7 January 1960, Vickers Viscount 802 G-AOHU was damaged beyond economic repair when the nose wheel collapsed on landing at Heathrow Airport due to ATC error.

On 21 December 1961, Cyprus Airways Flight 226, a de Havilland Comet 4B (G-ARJM) operating on behalf of Cyprus Airways from London to Tel Aviv, stalled and crashed on takeoff from Esenboğa Airport, Ankara, Turkey. The aircraft was destroyed in the crash killing 27 of 34 on board. The cause was attributed to a fault with the horizon direction indicator giving the pilot a false indication and therefore leading him to put the aircraft in the wrong attitude. BEA and their underwriters began action in 1969 against the manufacturer of the indicator. The manufacturer stated they would defend the action and show that the cause was the pilot suffering a heart attack and the crew being negligent with flightdeck procedures. On 4 July 1965, Armstrong Whitworth Argosy 222 G-ASXL crashed into a hilltop near Piacenza, Italy due to a navigation error. Although the aircraft was destroyed, both pilots survived.

The explosion was caused by a device under a passenger seat. On 4 December 1967, Armstrong Whitworth Argosy 222 G-ASXP crashed on a training flight at Stansted during a simulated engine failure, as a result of loss of control.
