Did a search of the pilots name and found this German website….its all in German, but it lists his plane’s s/n:42-51542 and lists my uncle as the Bombardier in the crew section. The comments translate to:
“The plane was hit over the target of Flak and immediately went up in flames. Parts broke off from the machine and threatened to fall on other bombers in the formation“Also says the Co-pilot, Navigator and 2 of the Gunners were killed. Notes say the copilot was injured and trapped in the cockpit, pilot tried to get him out but couldn’t.
