Could conditions similar to Hogan's Heroes really have took place?

Not really! Hogans Heroes is a great show (I am very much an addict) but it was clearly a comedy and most of those situations couldn't happen and if they did the prisoners would probably be shot or "put in the cooler" for a long long long time and they would only be able to do it that once. But then again "I know nothing"...hahahahahaha

It is possible that if a means of communication were established that POWs could occasionally slip information back to their side. It might just be lists of prisoners or any other relevant data they could gather.

One of the goals of escapes, besides getting Soldiers back into the fight, is to tie up enemy troops in searches for the escapees, and prevent them from being used at the front.

As far as a Hogan's Heroes style revolving door operation, it's pretty unlikely. The enemy troops weren't that lax or incompetent.

as great as the show was no i worked with ex british POWS including douglas Bader (Old Tin Legs )

he escaped 3 time the first time he was in Hospital and the RAF were given permission to drop a new set of legs to the Hospital he escaped that night got caught escaped again and was sent to Colditz Castle where he tried to escape again some of the great escape has some truth same as the wooden Horse and yes they were all trying to tunnel out

Bader had a radio in his tin leg all flying equipment had maps and compasses hidden in them

yes they did scrounge and spy and comitted sabotage as part of escaping thats why very few POW camps were Bombed the alliae knew where they were

they stole spent time in the cooler

but most of the movies are a collection of true stories embelished to make a great movie a ww2 friend of mine Loves the Great Escape and How steves bike changes from a tourer to a trail bike for the Jump

One reason the prisoners were smarter and more competent than their guards was that Werner Klemperer, who played Col Klink, only agreed to play the part if his character never succeeded in his schemes. That was because in real life, he was Jewish. So were Leon Askin and John Banner. Robert Clary, who played Cpl. LeBeau, actually was in a concentration camp during WWII.

Yes, just as it is entirely plausible that a robot from the future could be sent back through time to kill me in order to prevent me from leading a human resistance group to victory against cybernetic oppressors.
