Hardly a prospect for Bristol to Glasgow or London to Plymouth public transport - but what do members think of "United plans supersonic passenger flights by 2029" from the BBC» (British Broadcasting Corporation - home page)?

Could it be done and developed on that time scale?

Could it really be carbon neutral?

Is there a business case for doing it?

Quote
US airline United has announced plans to buy 15 new supersonic airliners and "return supersonic speeds to aviation" in the year 2029.

Supersonic passenger flights ended in 2003 when Air France and British Airways retired Concorde.

The new Overture aircraft will be produced by a Denver-based company called Boom, which has yet to flight-test a supersonic jet.

United's deal is conditional on the new aircraft meeting safety standards.

Most unlikely to be achieved in the stated time. I suspect that they have greatly underestimated the time required to design and build a supersonic passenger plane.
How long did Concord take ? And that had the backing of TWO governments, AND Concord would not be allowed to fly today, as safety requirements tend to become ever more complex.

And I do not believe the claims about carbon neutrality either. Despite the claims made about possible future synthetic fuels.

As for demand, there might be a market but I doubt it.

A proper intercity train has a minimum of 8 coaches, gangwayed throughout, with first at one end, and a full sized buffet car between first and standard.
It has space for cycles, surfboards,luggage etc.
A 5 car DMU (Diesel Multiple Unit) is not a proper inter-city train. The 5+5 and 9 car DMUs are almost as bad.
