Thanks gents. It did indeed crash into the River Forth, rather than the Firth of Forth, a few metres upstream from Kincardine Bridge. The wreck is still in the shallows of the river. The pilot, Squadron Leader R G L Baxter and one of the gunners, Sgt William Bartlett, were buried in the military plot of Grandsable (Grangemouth) cemetery. The others were returned to their families.
It's one of my medium term projects to build a model of this aircraft for Grangemouth Heritage Centre.
