Hardly any of my remaining friends can discuss the differences between a Comet 4B and 4C (length, wing span, slipper tanks); about the merits of the Dart Herald vs the F-27; the location of the exhaust stacks on the R-R Merlin engines on the Canadair DC-4M North Star/Argonaut (one of his favorites); the transport with the most completely different engines (Convair 240 series - 4 manufacturers); Stratocruisers - square windows, round windows, or both?; and he also loved Connies (of course!)  And, occasionally, I bested him in the discussion - but not often!

And so, Chris, R.I.P. dear, dear friend - I miss you so much.  More than a lot.  With whom can I continue our discussions on the airlines that chose the R-R Conway for the 707 (and DC-8) - and why.  And especially, which was the best paint scheme on the Bristol Britannia (clearly British Caledonian, Chris, with that great gold Lion on the deep Navy blue fin - sorry Chris, you're definitely wrong on that one!)
