1, I don't think we'd have been so stupid as to nuke a target as close to us as Berlin. Given the slightest easterly wind, it'd have been suicide.
2, the Victory concept was unremittingly awful, unworkable and would have made the Vickers Windsor look like a tremendous success... they never made a successful 4-engined type until the Viscount.
3, re 9 vs 617, there's a thread over on PPRuNe about the 30-year battle between them over the Tirpitz bulkhead, and the extraordinary lengths to which they went to gain and retain possession thereof, including a 9 Sqn Vulcan fuelled for Akrotiri declaring an emergency on takeoff from Waddington and diverting to Wittering, landing fully fuelled (without the aid of the brake 'chute), where it picked up the newly-stolen bulkhead from a Transit van that had raced down the road, as 617 had been searching every departing 9 Sqn Vulcan before takeoff... and when 617 got it back out at Akrotiri, 9 likewise searched every aircraft heading to Britain... but not the Shorts Belfast going to Masirah! Guess where 617 had hidden the bulkhead... finally, after 30 years and a great deal of use of power tools and explosives, a building at Marham was so badly-damaged in the theft of the bulkhead in the early 90s that the RAF Museum intervened and retook possession of it for display at Hendon, where it has remained ever since.
There's a similar story about 43 and 111 Squadrons at Leuchars, involving a Navy Wessex from Yeovilton, some graffiti vandalism, the theft of 43's squadron mascot, and a supermarket frozen chicken...
