Two Hawk trainer jets from RAF Valley in north Wales came within 100 feet of a near miss, an accident report has revealed.

The report from the UK Airprox Board reveals that the two jets were 25 miles south east of RAF Valley on Anglesey when the incident occurred.

Both pilots reported that the risk of collision was "very high".

The accident happened on 10 November last year.

'Crowded'

Both planes were at an altitude of between 7,000 and 7,400 ft.

The UKAB - part of the Civil Aviation Authority - concluded that there had been an "actual risk" of a collision.

The report said airspace in the vicinity in which crews conduct training was "at a premium and can become crowded all too quickly".

"A closing speed in the order of 700 knots does not leave much time to react and members believed that in this incident avoiding action was more an instinctive reaction than anything else," said the report's authors.

The report concluded that RAF Valley should take "positive steps to de-conflict combat training".

"However the available measures to separate tactical formation training are limited whilst still permitting the aim of the mission to be achieved," said the report.
