The UK Airprox Board (UKAB) released a report over the weekend which described how a Boeing 777 almost came into contact with the drone at 6,000ft over Potters Bar.

“The drone was being flown above the maximum permitted height of 400ft and within controlled airspace such that it was endangering other aircraft at that location,” the UKAB report said.

The report also revealed that the drone and jet were only separated by 20ft, meaning that there was a “high” risk of collision and a risk to the overall safety of passengers on board the flight.

The information comes from the B777 pilot’s account of the incident in February to UKAB, which points to a “definite risk of collision”.
