One further thought - how did our budding avaiator plan to invade UK airspace from the direction of Europe without clearance at what was then the height of the Cold War?
Having spent a week at each of five different serving RAF stations in the 1950's as a CCF cadet on annual camps, I would say that the best time for such an unauthorised flight (or the Russians!) to invade would have been over a weekend, preferably on the Sunday ... From personal observation the stations I stayed at "died" at weekends, including one Vulcan base and one busy fighter base!
Unfortunately, J/T Neville chose to make his abortive attempt on a Tuesday, so he was probably knackered anyway - just as well that he got bogged down without leaving the ground, perhaps!
