1 COURT Jet Substitute 17:43GMT
An RAF air traffic controller today appeared before a court martial charged with causing the death of two pilots in a double jet crash.
Flight Lieutenant Malcolm Williams, 47, was on duty at RAF Leuchars, Fife, on the day two F15C jets crashed into a Scottish mountain.
Lieutenant Colonel Kenneth Hyvonen, 40, and Captain Kirk Jones 27, of the United States Air Force, died in the incident at Ben Macdui in the Cairngorms during a snowstorm on March 26, 2001.
Flt Lt Williams, who had been providing radar information and was in contact with Lt Col Hyvonen, is alleged to have told the pilot to descend to 4,000ft when the minimum safe altitude in that area was 6,500ft.
The descent is said to have caused the deaths of the two pilots.
Williams faces an alternative charge of negligently performing in his duties as an air traffic controller.
He has pleaded not guilty to all charges.
...
The court martial, which is expected to last several days, opened today before seven senior RAF officers assisted by a judge advocate.
RAF Group Captain Alistair McGrigor, prosecuting, said Flt Lt Williams had “created a false environment and lulled the air crew into a false sense of security”.
He said the air traffic controller had responded “inappropriately” by telling Lt Col Hyvonen, the lead pilot of the formation, to descend to 4,000ft.
However, he said Williams was not solely responsible for the accident and conceded that the pilots were responsible for the avoidance of any other air traffic and the terrain.
The court martial heard that Lt Col Hyvonen had used an American phrase “minimum vectoring altitude” which Flt Lt Williams had not queried.
Lt Col Hyvonen had then asked Flt Lt Williams to confirm the descent to 4,000ft, which the air traffic controller did.
...
The court martial, before Judge Advocate Edmwnd Hoelwyn-Hughes, was to continue tomorrow at the Royal Navy base in Helensburgh, Argyll and Bute, Scotland.
