I was a student pilot in the early 80s and flew in the front seat of G-BECM out of Eastleigh Airport one Saturday - my first aerobatics lesson. It was then part of the Rothmans Aerobatics Team and spent a couple of days in Southampton on the way back to base in Wales (I think).
I'll never forget the experience.
Only yesterday I was looking at some old photos taken before and after the flight. Sadly, the transparency film has deteriorated badly over the years.
