An interesting story , but some confused reporting here, especially the bit about Sergeant Phillip's sister being told of the fate of her brother and the fact the the Germans had buried him with full military honours. These facts would surely have been known to her as Commonwealth War Graves have the record of his grave in Berlin War Cemetery where he is buried with other members of the crew. This cemetery contains the graves of many RAF aircrew who lost their lives in bomber raids on Germany. Here's the link

It's quite possible that the remains of a Lancaster could have remained undiscovered in dense woodland for so long, but there was never any mystery about the fate of the crew.
