As a private pilot, I had flown already several times over the Ruhr district before I knew that, at one time during World War 2, dams in the area had been subject to air attacks by the British.
As aviation interests me, I did a search about it on the internet, and the queries returned thousands of mostly British websites with stories, articles, books, movies, TV-shows, etc. about the "Dambusters". A raid against German dams had taken place, and it is a heroic story in Britain, although it is not commonly known in other countries.
Most works on World War 2 European air war make mention of the Dambusters raid as a footnote if at all. The official assessment of the bombing campain (the British Bombing Survey Unit, The Strategic Air War Against Germany, 1939 - 1945) neglects to mention the raid entirely.

It was unavoidable to notice that the raid is fiercely debated in Britain, and further reading was required. For those who are interested, I made an extra page which reflects on the impact against the described goals and predicted results of the air strikes that were drawn-up during the preparation of the operation (link at the bottom of the trip report).
