This is just as meaningful as when - 20 years ago - the CEO of American said they were buying the Boeing Sonic Cruiser.

That is to say, basically meaningless...:ugh:

Was that Darth Crandall that said that?

American Airlines orders 60 Overture supersonic jets

The revival of supersonic passenger travel, thought to be long dead with the demise of Concorde nearly two decades ago, could be about to take wing as American Airlines has put in an order for 60 aircraft capable of flying at 1.7 times the speed of sound…..

In June, United Airlines said it had signed up to the venture as a launch customer, putting a firm order in for 15 of Boom Overture planes, with an option to take another 35. United’s great rival American has now trumped it with a firm order for 20 and an option to take a further 40…..

Japan Airlines made a commitment to take 20 of Boom’s planes as long ago as 2017…..

So the "man made" climate change topic is officially put to rest now as supersonic travel is bound to return and airline PR departments seem to consider these announcements do more good than harm?
I still consider Boom to be vapourware.

Wikipedia quoting Aviation Week says "Design changes announced in July, 2022 included an increase in the number of engines to 4 to allow for smaller less technically challenging engines and to allow takeoff at derated levels to lower noise; and redesigned gull form wing and fuselage to reduce drag." It's also acquired a Concorde-shaped wing since it was first designed. So that is a change in fuselage, wings and engines. In lots of ways they must be starting from scratch.

A technology demonstrator (with a delta wing, the former shape of fuselage and three engines) was rolled out in Oct 2020 and has yet to be taxied. When announced its first flight was scheduled for 2017.

I think the Boeing 7E7 was a much safer bet.
