There was a great program on the Smithsonian Channel recently about what happened to the 617 squadron after the dam buster raid. Having put together a squadron capable of precision bombing, the RAF naturally wanted to keep using it's ability. Very interesting stuff that I'd not heard of before (not all successful raids though, and losses continued to be heavy).
I don't recall exactly what the program was called - although I saved the program on my DVR, I'm not currently at home to check it.
Here's a tip: switch off your TV and read the book - The Dam Busters by Paul Brickhill. The story of 617 is in there right up to the end of the war. Some of the stuff they did later was even more dangerous than the dams raid e.g. the Dortmund-Ems canal attacks. Men of steel.
