Excellent prog...especially when you consider the dross that passes for TV these days.
I loved the "hurry and wait" bit as they went for the live drop, with associated goatf**k over the unbalanced bomb. Most on here will have seen similar during their time in the mob.
If you've not read it I strongly recommend "Dambusters" by Max Arthur, Virgin Books 2009. A gripping series of eyewitness accounts, including people like the AA commander from one of the Moehne Dam towers. What comes over in this book is not just the incredible skill of the crews, but also what a ruthless bunch Gibson had turned them into. Many of the gunners took extra ammo as a low level run in and out of Germany was just too good a "shoot em up" opportunity to be missed.
Interesting to note that Scheer never understood why they did not come back and bomb the crap out of the repairs to finish the dams off. As it was the effect on industry was negligable, but the moral boost was immense.
