As a BA 'Junior Jet Club' member in the 70's/80's, I recall that the club magazine contained an article about a member that had built a Trident 3 mock-up in the family garage. Leo Bud, the then president of the club went to visit & there was a photo of the two of them in it. The lad who built it had ambitions to fly & I always wondered how he faired.
I wonder if he was the same Max Kingsley-Jones who now writes for Flight International ?
