In the days when students or schoolkids had summer jobs, I worked on Concorde in the wind tunnels at a company called ARA at Bedford. We ran several different trails on models in the supersonic and transonic tunnels and yes I have to agree with you, she was a work of art as well as being well ahead of her time. I also reckon you have not seen engineering until you have seen Rolls Royce engineering, The models of the intakes we put through the supersonic tunnel, in an effort to get the variable geometry and the pattern of shock waves within the intake right, were mind blowing in their precision.
