I see all the old friends recalling their past here
My first time in was on British Eagle One Eleven G-ATPI in September 1968, coming down from Liverpool. A surprisingly high speed turnoff/swerve from 28R. Did they do those so long ago ? Yes they did.
The sad bit is, despite NOT being a spotter, that registration is not in any notes or anything but is in my head, and has been so for nearly 40 years.
