I believe that the RAF BoI is likely to conclude in the near future.
If the reports of the USAF inquiry are true - quote :
"The US Air Force Accident Investigation Board found the crash was caused by a “breakdown in terrain avoidance responsibilities between the pilot(s) and air traffic controllers on the ground”.
then they also seem to disbelieve the very credible eyewitness reports that saw the aircraft already engaged in low flying 9km east of the crash site and on a westerly heading.
This does not support a straight line descent in IMC direct into terrain on a northerly heading
Will the new RAF BoI findings also disregard the eyewitness accounts( the first BoI didn't even bother to interview them)?
It should be appreciated that eyewitnesses saw 2 twin tailed aircraft flying in very close formation. They were adamant that they were not Tornados. The closest sighting was 40yds !!!
The only other aircraft in that low level are that day were 2 Tornados which were flying in loose trail and which landed some 50 minutes prior to the last radar sighting of the F15s.
