Air Raid on Bonn 24 August 1944?

[onavik]

A friend asked if I could help him with his Research - and he provided the following information:

- Looking for a man called Jean-Pierre (French, Canadian or Belgian - or maybe just a nickname?)
- Crewmember (gunner) on a raid on Bonn 24 August 1944
- The bomber had a 4-man crew
- Crashed near the Alps after the attack
- The Squadron operated out of Western France

I haven't been able to find any information concerning an air raid on Bonn on this date. While the information seems to be a little 'inaccurate' in some areas, I have a hunch that we're looking for a light bomber squadron of the 9th USAAF. Maybe a B-26 squadron, even though the B-26 had a bigger crew than 4...
(Or possibly Free French?)

Any information on the person/aircraft/unit - or advice on how to proceed - would be highly appreciated!
