Yes, I do remember the smaller BA 747 Upper deck. Used to fly quite regularly to Dulles on them in the early nineties. Cradle seats, an extensive menu printed on nice cards, a washbag that was worth keeping and a nice cozy environment but not the coffins that we now have to reside in.
To contrast and slightly off topic, I've just flown into MSP on Northwest for the first time. They go out of T4 which, after all the BA years seems strange and somehow "wrong".
The business service on Northwest? "Whaddya want? Fish or meat....?"
"Sigh"
