I was sent to ( private but not posh ! ) school near Leeds-Bradford & ‘Lived’ at the airport most weekends in ‘73 / ‘74.
Northeast had a maintenance hangar & after a while of us asking to look at the aircraft , the techies were used to us and we were allowed in and onto the Viscounts.
Leeds - Bradford had a lot of Viscounts back then & we also knew that if Leeds United were playing away somewhere distant , we could look forward to a visit from one in Alidair markings.
I have been in lots of viscounts but never flew in one , sadly.
I DID used to fly home to Glasgow in a Dart powered HS-748 tho’.
