What happened
On 4 June 1967, a commercial airliner operated by British Midland Airways suffered a catastrophic failure while flying over England. The aircraft, identified as Canadair C-4 Argonaut with registration G-ANAV, was carrying passengers and crew on what was designated as Flight 542. During the flight, the plane lost control and descended rapidly, ultimately impacting the ground near the center of Stockport in Cheshire.
The crash resulted in significant loss of life. Of the 84 people aboard the aircraft, 72 were killed. The remaining individuals on board survived the initial impact, though the event is recorded as one of the most severe aviation disasters in the United Kingdom's history at that time. This incident occurred just one day after another major accident involving an Air Ferry DC-4.
