Luftwaffe Personnel spying for Allies?

[Flitzer]

There's another humint that's not mentioned too often, I just ran across a great example today reading Impact - the history of Germany's V-Weapons in World War II.

The following quote is from the book:

"On March 22, 1943, MI recorded a conversation between German Generals Ritter von Thoma and Ludwig Crüwell, who had been captured in Africa. The two men, obviously aware they were being monitored, spoke in hushed tones, and parts of their conversation went unheard even by the sensitive microphones in the room. Crüwell had been captured in May 1942 and von Thoma in November. In bringing Crüwell up to date, von Thoma told of a large rocket he had seen tested, presumably at Kummersdorf, with F.M. von Brauchitsch. The weapon, according to von Thoma, went into the stratosphere and had unlimited range."

And that reminded me of the classic from "The One that Got Away", where the two German POW pilots leaned out of the window to have a discussion -- there was a microphone under the window sill!
