Final Briefing by Anthony Saunders features the Dambuster Lancaster of Guy Gibson just prior to the raid.

RAF Scampton: 16 May 1943 20.55 hrs - Guy Gibson readies his crew to climb inside their waiting Lancaster – AJ-G ‘George’. A red flare will soon curl skywards, burning brightly against the sun’s fast-fading rays; it is the signal to start engines and at 21.39 G-George will get airborne, leading the first wave of three aircraft. For the crews of 617 Squadron the weeks of intensive training were now over – Operation Chastise was underway. 

Everyone at Scampton suspected that something big was about to happen. The crews of the recently formed 617 Squadron, hand-picked by Wing Commander Guy Gibson, had been training hard for weeks and the rumour on the grapevine suggested it might be the Tirpitz they were after. But then, late in the afternoon of 16 May 1943 came the call over the station tannoy that they had all been waiting for: ‘All crews of 617 Squadron to report to the briefing room – immediately.’

The buzz of excited conversation dropped into silence as Gibson addressed them, and the secret was shared: their small force was about to attack the major dams of western Germany. It was what they had been waiting for and they would go that night.
