An onboard collision warning system could have helped prevent a mid-air crash between two RAF Tornados off the coast of Scotland in which three men died, according to air accident investigators.
A report into the crash involving the two Tornado GR4s over the Moray Firth on July 3, 2012 found there were 17 contributory factors, including the lack of a collision warning system (CWS) on both aircraft.
A system is due to be installed in the next year after several delays.
Flight Lieutenant Hywel Poole, 28, Flt Lt Adam Sanders, 27, and Squadron Leader Samuel Bailey, 26, died in the crash.
A fourth crewman was badly injured.
The men were all based at RAF Lossiemouth in Moray.
