Did You Wonder Why Supersonic Airliners Stopped After Concorde?

I wondered for a long time why Concorde went away and no one else entered that space.  I assumed that it was because the SST was government-subsidized.  It was.  The U.S. SST did not get U.S. government loan guarantees and died.  Concorde did get aubsidies rrom Britain and France, and was not financially viable.

The concept was good.  If I could get to Paris in five hours not ten,  it would be a lot more attractive, even at a very high price.  (I have reached the age where money is far easier to get than time.)

It turns out that there were some regulatory obstacles in the way as well.  Trump decided to fix that.  He is directing repeal of the ban on cross-country supersonic travel.  My recollection is that part of what crippled Concorde was that it could not provide transcontinentsl service.  Imagine Los Angeles to NYC in 90 minutes.  (From one leftist hell to another too quick to watch a movie.)  One with longer range could make LA to London a relatively tolerable trip.

I remember news coverage of neo-Luddites protests of the Concorde's arrival at JFK because of noise.  The coverage included the delightful fact that the protesters did not notice its arrival.  We're they actually upset about noise? Or technology?
