Main causes of jet 'near miss'published at 10:39 British Summer Time 24 July 2017
A report into a "near miss" involving two US Air Force jets from Lakenheath and an RAF refuelling plane off the coast of Norfolk says that two causes were uncovered, external by RAF investigators, as well as several "contributory" factors.
The "causal factors" were that the controller did not effectively prevent the F15 from entering the airspace around the RAF Voyager plane, and the F15s entered the Air to Air Refuelling Area (AARA) unaware that it was active.
It emerged during the investigation the F15 pilots only had information about AARA activity which involved USAF assets.
A recommendation regarding the "filtering" of this information has subsequently been adopted.
The investigation also identified confusion among a number of parties over the naming of certain airspace areas.
When the F15s requested permission to operate in the "Wash" and the "Northern half of the Wash", the controllers assumed they were referring to the "geographic Wash" rather than the "Wash Aerial Tactics Area".
