The Dam Busters

There was no follow-up raid because aerial photography showed that the new anti-air raid defences on the dam installed after the attack would have made a second raid suicidal.

The system devised to get the height right was, in the film, said to have been thought of by the 617 Sqn crews following a visit to the theater. In reality it was devised by the 'boffins' at Farnborough.

Blu-Ray edition opening screen: "While we acknowledge some of the language used in The Dam Busters reflects historical attitudes audiences may find offensive, for reasons of historical accuracy we have opted to present the film as it was originally screened."

This refers to the fact that the protagonist, Wing Commander Guy Penrose Gibson's, dog is named "N-Word." In addition, the dog's name is used during the raid on the dams as code indicating the dam(s) have successfully been breached.

Prints distributed in the United States by Warner Brothers added a shot from Fugitivos del infierno (1942) showing an early model B-17 Flying Fortress crashlanding in a forest.

Edited into Fortaleza del infierno (1968)
