If you like that thread, I can really recommend this book: Concorde New Shape in the Sky by Kenneth Owen.
There are two editions of the book. The first edition is super cheap (eg. 29p + postage: https://www.amazon.co.uk/d/cka/Concorde-New-Shape-Sky-Ken-Ow...). There was a second edition written after the 2000 accident in France, which is supposed to be a better version, but I have not read it because it's out of print and considerably more expensive.
Two things I remember: the statement that by the end of the engineering effort "everyone was exhausted and nobody was really in control" (paraphrasing slightly from memory)
and a curious interview with a (British) engineer who was very concerned about keeping technologies proprietary at the national level--he seemed to be happy for UK firms to share know-how (as I believe is traditional, up to a point, in engineering culture) but god forbid it should be shared with another country's engineers. Shades of the Brexit mentality.
That "concern[] about keeping technologies proprietary at a national level" is very common for nationally-funded aerospace projects and research. Whether you think it is a good or bad idea, it is common, wide-spread, and long-running.
