A squadron of fighter jets was involved in a near miss with a coastguard helicopter during a rescue mission in the Highlands.

Four F15s flew within 3000ft of the coastguard aircraft, a distance they are capable of closing in just over a second.

Their pilots did not see the S92 helicopter at all during the incident over Glen Feshie in the Cairngorms in March.

It was involved with a search and rescue operation in the area at the time.

The UK Airprox Board, which investigates near misses in British airspace, said the safety of the aircraft was at risk.

In a report published on Monday, the panel concluded: "Some members had the view that at [3000ft] the separation might not be considered unduly close and that there had been no risk of collision.

"Others felt that the overtake speed of the F15 formation, along with the lack of any visual sighting, had resulted in a collision being avoided only through providence.

"Ultimately, after a protracted debate, the majority of members agreed that there had been a risk of collision."
