Good points
Did give lots of good information about the raid, such as the difficulties faced by the pilots.
The end of the DVD gives the reasons why this raid can be regarded as a success.
Bad points
Pity this was only about 50 minutes long. It had excerpts from the movie, but did not say these were excerpts and not reality.
Other
Good idea to watch this DVD after watching the movie. The DVD assumes you know the basic facts about the raid.
Had hoped it was a movie, it turned out to be a documentary.
Worth watching as an adjunct to the film and the other documentary available. The personal recollections are valuable historical records.
Was looking for the movie, but the documentary was very interesting, from the bomb design to the bravery of the flight crew and a look at the German landscape.
