Thanks to all the replies, I think we can call this solved, it is Lakenheath Airshow 1988, although I cant remember going ((I did go to a lot in those days!)
Thanks to “Archer ” for the participant list it help nail the location, I have other unidentified airframes which I have tied up with the list, A later slide in the roll (Below) shows a F16 with the Phantom which is also on the list (288)
Thanks again 😀
