If you read my earlier post you will understand that I put it forward as being a possibility.
At least that was the intension. He force landed on the date you asked about.
He was of a Group involved in operations on that date.
So I put it to you that it is a possibility that he was involved, a/c damagedperhaps by enemy action and somehow managed to survive , return and force land/crash land.
Otherwise perhaps the pilot you refer too as claiming a P38/F5 on the date you give must have imagined it as there were no other losses other than those already noted in the thread as far as I am aware. 25th August '44 42-13309/Jensen, 6th, August '44, 42-67822 and 43-28529 both in the UK and 43-28795 in Manfredonia, Italy. Oh also there was the P-61, 42-5545, MACR 8706.
