Have you read my previous postings which referred to a radar recording at Prestwick?
An article by a reputable journalist implied that the a/c was observed sufficiently close to the Mull to conclude that the last part of its flight was very much straight in.
The interesting thing is that the very existence of this recording has been denied by many on this thread and yet the journalist is adamant that his contact was in a position to know.
It is typical of the lack of positive feedback on this thread that no one mentioned that there had been a radar at Macrihanish – all the learned contributors mentioning only major sites nowhere near as being the only radars in the area.
One would have thought that, with the sometimes intense air activity in the area (eg when exercises held) that there would be low level coverage.
