I still find it truly remarkable that an airliner that first flew 5 months before Neil and Buzz set foot on Tranquility Base, is still around at all!
I never got to fly in one, although I have flown in a A380, and the Dowager Queen of the Skies, the VC10!
I saw my 1st 747 in the summer of 1970, coming home from a school trip to London..it was so unmistakeable, cruising around Ockham stack..ahh happy days!
