There is a wonderful gentleman called Gordon Lyons who hosts an Air Crash Scotland site in his own time. I believe he would be very keen to include details of this crash site if someone would forward him the details. My father also piloted a Mosquito that crashed in Scotland in 1943. Fortunately (for me in particular) both he and his navigator parachuted out relatively safely. Details of that crash site are at
DH Mosquito MM244
It also contains a photo of a 544 Squadron detachment at, yes Leuchars, in 1945.
