Hi Rob, please thank your dad for me. I've got the original newspaper cutting in front of me and it says that the crash happened over Averham (I've never heard of it so don't know how far from Newark). But it goes into a lot of detail about Newark - the mock attack was to be at Newark, where "the bombers were trying to obliterate Staythorpe power station" - and this was 1/2 mile from the crash. It includes accounts from witnesses in Newark - so I guess your dad's memory is of this crash.
Apparently, ground control's involvement was that it sent one plane up as another was coming in to land - it was thick fog that night, according to the reports that Rowley found for me, which perhaps explains the mistake.
I heard about the court marshall only last week so I don't have any more details about that but the person who told me about it was correct in every other detail, right down to date and time, so I'm assuming it's correct for now.
Thank you *very* much for your post.
Jackie
