My my, what an Angry Young Man our jondc9 friend is becoming !!
... and so sarcastic ...
... and a bit short on facts, too - I don't recall that BOAC ever flew the Trident ... ?? Better ask one of the Few about that, I guess ... their lovely old Groundgripper ...
I also seem to recall that the VC10 (aka KTNC Mk1) was actually more economical on fuel on three engines, than four ... but never mind, I'm sure he doesn't want to be confused with the facts, as his mind is already made up ...
Thought for the day ... 'tis better to remain silent and be thought a fool than to open one's mouth and remove all doubt ...
