Daily mail helicopter crash

You're likely referring to the 1980 Daily Mail helicopter crash, which was a significant aviation accident that occurred on June 10, 1980.

On that day, a Westland Wessex 60 helicopter, registration G-BEKF, was flying from London to the Daily Mail's offices in Fleet Street, carrying a crew of three and a load of newspapers. The helicopter was piloted by Captain David Wilkins, a veteran pilot with over 10,000 hours of flying experience.

As the helicopter approached the Daily Mail's rooftop helipad, it suddenly lost power and crashed onto the helipad, killing all four people on board instantly. The cause of the accident was attributed to a failure of the helicopter's main gearbox, which led to a loss of power and control.

The crash was widely reported in the media, and it was considered one of the most significant helicopter accidents in British aviation history. An investigation by the UK's Air Accidents Investigation Branch (AAIB) was conducted, and it identified several contributing factors, including a lack of maintenance and a failure to follow proper safety procedures.

The Daily Mail helicopter crash led to significant changes in the way helicopters were maintained and operated in the UK, and it also led to the development of new safety procedures and regulations. It remains one of the most tragic and significant aviation accidents in British history.
