An inquiry into a Tornado crash in Argyll which killed two RAF air crew has found the plane ran out of space to turn during a low-level flight.
The F3 Tornado flew into a hillside near the Rest and Be Thankful beauty spot in Glen Kinglass on 2 July 2009.
An inquiry concluded the crash was caused by "controlled flight into terrain" but did not apportion blame.
Pilot, Fl Lt Kenneth Thompson, and his navigator, Fl Lt Nigel Morton, died in the crash near Arrochar.
The crashed plane was one of two Tornado aircraft flying on a routine low-level training exercise out of RAF Leuchars.
It came down in Glen Kinglass at about 1145 BST, approximately 14 minutes after take off.
The inquiry report into the crash said that once the aircraft had entered into the final turn it was effectively all but impossible to achieve the turn safely.

As a consequence, it crashed into the north slope of Glen Kinglass.
The second Tornado crew witnessed the crash and took "immediate recovery action" before returning safely to RAF Leuchars.
The inquiry report concluded that the aircraft's flying control systems, engines and structure were serviceable and all critical systems operated correctly during the flight.
It made a total of 26 recommendations largely relating to aircrew training and check and assurance processes.
'Specialist skills'
The Ministry of Defence said these were being addressed and would implemented "as soon as is practicable".
Leuchars Station Commander Air Cmdr Richard Atkinson said: "Thankfully, such incidents are rare, but this sad event reminds us of the risks involved in military aviation.
"It is vital, however, that the Royal Air Force continues to train its aircrew in the specialist skills of low flying in order to maintain its ability to operate effectively in a range of scenarios and which, for RAF Leuchars, means being able to maintain aircraft on Quick Reaction Alert 24 hours a day.
"Such training activities also ensure that our pilots and navigators remain among the best in the world."
