Don't know if anyone can help but i have been trying to find out what type of aircraft was 'dog fighting' with a Tornado over Northumberland last week. I have only just joined this forum (specifically to find out what it was) and cannot fugure out how to post a picture yet. It was larger than the Tornado and had a very similar look to a Gulfstream Jet. It was BLACK and the tornado tracked it for about 15 minutes before the headed out to sea adjacent to Boulmer RAF Station. I have 4 independent witnesses who were present at the time. Any ideas?
