Fantastic memories, here - many thanks for uploading all these photos!
I have a few from 1985-1992ish, so will have a look through them in the next couple of weeks and hopefully get them posted. I'm sure I have one of an Ambassador B752 next to an Airtours one which will hopefully be of interest to you.
As much as I liked the Ambassador colours and seeing their 757s, I was much more excited when a new 727 operator appeared in 1994/95 - Sabre! Standing in the field near the metro line and having one of these or a Maersk Air (UK) BAC One Eleven taking off was one hell of a buzz! Happy days...
