Re: The most amazing engineering
Sorry, Lost all faith ... but those situations do not pertain. Every last one is a straw man you constructed to make some point lost in the blither.
Smallish airfields were not host to Concorde. It flew internationally, so it required an "international" airport at which to drop anchor. Pesky thing, national immigration requirements. And if you think Concorde was loud, you should have heard that Phantom - standard issue at the US airbases in Norfolk when I were a lad. Or a Shackleton taking off for coast watch duties.
Your point about choices being made in the "now" conveniently ignores the facts that 20 years down the road you are living in it and it is "now", and that the Steel Mill requires a re-zoning that will take over a year to complete and in this time of instant communication would never be able to be done quietly.
And if you can't figure out the issues with living in an area re-zoned from commercial to industrial use, you have to take what's coming. usually a whacking great property tax break for having a steel mill next door, though the mill would probably want to buy you out so your hovel could be turned into a storage shed for coil steel.
