I don’t think so.
The wreck was found only about 9 NM from the location where it had been bombed by a British B-24. The crew was pretty sure they had sunk it, but the wreckage was never found - until now.
I suppose it is possible that it escaped the bombing, completed a run to S.A. and then on its return trip sank at essentially the same coordinates where it had originally been attacked - but I consider that highly unlikely.
It looks like “The Boys from Brazil” was fiction after all...
I know that there was more than one sub. Another one was intercepted and the men were captured. They claimed to be heading to S. America. I’ve never seen anything that said how many of these subs there were.
