Concorde - another singularity
While both "superpowers" built and operated large Mach 2-capable aircraft for war, I've long felt that another remarkable feature about Concorde is that it was built for peaceful purposes. Neither the Press nor other media have noted this, except indirectly - perhaps feeling it would be non-PC to do so. Building an aircraft for the safe and regular transport of passengers is a whole lot different from designing and building a bomber, and for me, this has always been a major "plus" for "the most beautiful aircraft ever built" ...
The US and USSR supersonic bombers also probably flew/fly far fewer sorties/hours than the Concorde fleet.
Credit where credit's due, eh ?
