An interesting article on the BBC website regarding the search for a prototype Victor B2 on 20 August 1959 which vanished during flight trials with the loss of 5 crew.

Later in the article it states "It gave British authorities enough information to be reasonably satisfied about the cause of the accident. It was concluded that only minor changes were needed to resolve the problem that caused the crash, allowing the bomber to enter service in February 1962."
I have never heard of this incident before even though I flew with a lot of ex-Victor aircrew on the tanker fleet. As well as making fellow PPRuNe readers aware of the article, I wonder if it would stir any interesting memories that others would find helpful?
I'm mindful that the 1950s was an era when a lot of lessons were learned about metal fatigue and stress with Comet and Valiant particularly.
