Recommendations included an urgent call for cockpit voice recorders and for closer co-operation between the Civil Aviation Authority and British airlines. Although the report covered the state of industrial relations at BEA, no mention was made of it in its conclusions, despite the feelings of observers that it intruded directly and comprehensively onto the aircraft's flight deck. BEA ceased to exist as a separate entity in 1974, when it and the British Overseas Airways Corporation merged to form British Airways. A recommendation of the report that all British-registered civil passenger-carrying aircraft of more than all-up weight should be equipped with cockpit voice recorders resulted in their fitting becoming mandatory on larger British-registered airliners from 1973.
