This looked like a recently produced programme and I thought it did a good job of recounting the events. Of course, historical accuracy is always a contentious issue and I don't think 9 Sqn or their association will be too pleased with almost all the emphasis going to 617 Sqn.
However, it is indeed a remarkable feat to drop bombs ballistically from 15,000ft and score direct hits on 3 out of the first 5 bombs.
The new(?) information regarding the fighter wing at Bardufoss & the English-sympathising German radar officer was very enlightening and just proves how close we came to disaster but for a few other minor events.
