....I cannot imagine they carefully recovered all the human remains from obliterated wreck sites...
An intact body is one thing. An unrecognizable one or body parts is a other.
We don’t even know what exactly was remaining, what the crash site looked like, and if the Germans were even around when it crashed. All of this is sheer speculation.
3 condoms? How unusual was that?
I imagine German officers (and enlisted) were issued condoms for disease prevention. Truth be told US soldiers were issued condoms as well.
