Pick ur brains?

Hi all,I was living in Hertfordshire (Bushey)until last year and in either 1994 or 1995 we had a flyover of (Harriers and other planes) 😮 All I remember is,they were REALLY noisy,there were lots of them,and I think it was something to do with some celebration or other for the queen???I have tried umpteen sites and Herts newspapers but can’t find anything.This isn’t really important,just something I was telling the boyfriend.So if anyone knows what I am waffling about could they please help? 🙂 Thanks,
Helen.
