Re: "Noisy" Concorde
Indeed; those who complain about Concorde's noise are almost certainly too young to remember "proper" jet engines, as opposed to today's fanjets. The BAC 1-11, Boeing 707, DC-8 and VC-10 were all way louder than Concorde, especially as you got further away from the runway, as Concorde had a very aggressive climb profile, which minimised the noise footprint if you were more than a mile from the end of the runway.
Until 2013 it was still possible to appreciate just how noisy the VC-10 was. I was standing in Port Meadow in Oxford, approximately 12 miles from Brize Norton, listening to a VC-10 doing circuits; it was possible to hear it clearly through every stage of the circuit!
