Your info is wrong! Fairey Delta2 flew at 1,132mph and gained a new world record. BUT........FD2 was only a small part of the Concorde story, but a very important one. The HP115 was spectacularly useful, and very very cheap. The Vulcan was a test bed for the Olympus 593 engine - fitted underneath the Vulcan. The telemetry fitted on the Bristol 188 was a major boost for Concorde's development. Indeed, it carried over 12 tons of test equipment on board each of the prototypes.
I don't think it was that technologically brilliant. It is just a lump of metal. It represented an inglorious industrial/political era that took the country decades to escape from.
It was and is gloriously technologically brilliant, like the TSR2, but to send Concorde to the scrap heap with so much life left in it is criminal.
