All I want to know is how safe it is, and how loud the sonic boom would be when flew over, not how expensive the ticket would be, nor "Will regular passengers be able to handle the physical effects of such high-speed travel."
Won't happen. The primary reason the Concord failed was that they couldn't make enough money. Running engines to push a plane that fast are super expensive.
Let's not forget that the Concord failed in 2003. I wonder what started happening around then that made that actual flying part a smaller fraction of the overall time spent traveling.....
Even if you can step through a portal and instantaneously get to London from NY, if you still have to go through the rest of the airline process the time savings just isn't that huge.
The one where a part from another plane fell off and got ingested into the Concord's engine? It's hard to see that as Concord's fault, but there was significant loss of life and reputation. But that really shouldn't be characterized as a Concord failure.
Because it turned out that no one really needs to get between the UK and the US that quickly. If they do need to get between the UK and the US they're prepared to pay less for it to take longer because the price difference is substantial.
