USAF investigators are to re-examine a crash which claimed the lives of two Suffolk-based fighter pilots.

RAF air traffic controller Flight Lieutenant Malcolm Williams was yesterday cleared of causing their deaths after a court martial in Helensburgh, Argyll and Bute, Scotland.

Lieutenant Colonel Kenneth Hyvonen, 40, and Captain Kirk Jones, 27, both based at RAF Lakenheath, were killed on March 26, 2001, after their F-15C fighter jets crashed into the snow-covered mountain Ben Macdui, in the Scottish Cairngorms.

Flt Lt Williams, 47, was charged with causing the death of the two pilots, along with an alternative charge of professional negligence. He denied both charges, and, following a 22-day court martial, was acquitted on both counts.

A spokesman for the United States Air Forces in Europe said their own investigation into the accident would reopen in the light of the jury's decision.
