Glider pilots have been told to register their flights after a near miss with two F-15 fighter jets.

The British Gliding Association has now advised its members to issue special notices to other aviators when flying in large groups such as competitions.

It comes after a pair of of the US Air Force planes, flying at 380mph, came within a split second of smashing into a glider, a report has revealed.

One of the US pilots estimated that the gilder had flown just 100ft beneath them and just 330ft ahead.

The UK Air Proximity Board (UKAB) revealed the incident happened on August 14 last year as the fighters were coming in to land at their base in RAF Lakenheath, Suffolk.

The jets were flying at 3,200ft at the time over woodland to the west of Thetford, Norfolk.
