Gentlemen,
Thanks for checking for me and especially for ruling out the 55th FG history as a source. I can understand why Gray might not have mentioned such a small skirmish. I did find in the WWII Aircraft Performance website an excellent analysis of the 24 April 1944 air actions around Munich itself, if not where Friedrich Heilmann's fight took place. Attached to the article was the text of the VIII Fighter Command's Narrative of Operations for that day, and that report is extremely useful.

The evidence does point to the 55th Fighter Group, with P-38s, that dived on a group of ME-109s that were attacking the rear box of the two lead B-17 combat wings from the 3rd Bomb Division heading in to bomb Friedrichshafen. The 109s "split S'ed for deck," 343rd Yellow flight making the claims of 1-1-0 air.

I still hope to find the reports for the 55 FG and 343 FS for that day and the encounter reports for Lt. Porter and Lt. DeYoung. I would much appreciate any advice as to where they might be located.

Thanks again.

Best wishes,
John
