Great thread - and it inspired me to buy Ted Talbot's book.
I used to work with a design engineer who worked on the intake controls team - many an hour at work was spent listening to his stories!
But back to the thread....
In T. Talbot's book he mentions that above Mach 1.6 (?) Concorde was certified as a twin-engined aircraft due to the common intake.
As I don't know how in those days the equivalent of ETOPS was - how were the diversion airfields worked out? As today (say) ETOPS 180 is somewhat different if you're at Mach 0.83 or 2.02 :-)
Thanks!
