Wensleydale:
XL 385 was part of Scampton 'Wing' and, as such, was not allocated to any particular Sqn. But at the time, the aircraft was in the hands of a 617 Sqn crew (Bill Taylor's, I think). So, if you want to associate the demise of 385 to a particular squadron, then it has to be 617.
There was an ATC cadet on board when this dramatic and potentially life threatening incident occured. He must have wondered if he was aspiring to the right profession
