Biofuels is ecological fraud. It is not sustainable. And is there a synthetic fuel plant with zero impact at any scale already? No, this is just wasting more fuel for the heck of it.

Are you saying that sustainable synthetic fuels can't exist? Or don't current exist? Because those are two very different statements.

Well, it requires a lot of power, so building a large plant will be difficult and expensive.

Overture is being designed to carry 65 to 80 passengers at Mach 1.7 over water — or twice the speed of today’s fastest commercial aircraft — with a range of 4,250 nautical miles. Optimized for speed, safety and sustainability, Overture is also being designed to fly more than 600 routes around the world in as little as half the time. Flying from Miami to London in just under five hours and Los Angeles to Honolulu in t…

> over water

All the imagined routes are over large bodies of water. Is it key to the functionality or intent of the aircraft in some way? Why not NYC to LAX in 3 hours?

Lithium based batteries don't produce power.

If this is achieved without afterburners (as I understand it is), then yes, this is an immense difference in fuel consumption and radically impacts the economics.

Concorde only used afterburner(en_us)/reheat(en_uk) for a small part of the acceleration phase of the flight not for cruise.

It's en_gb and not en_uk (although UK is exceptionally reserved [1], and we recently begun using UK on car nationality identifier stickers).

> coach class all the way Has there been a render of the interior or something?

There is on the Boom site, and it certainly doesn't look like regular cattle class https://boomsupersonic.com/static/images/overture-experience...

I can't see how that seat could possibly transform to lie flat and it's a dud if they try to get people to pay big money for non-lie flat seats.

Because of the sonic boom, you can't be flying over inhabited areas. Regulations prohibit that.

ah, neat! looks like they recently switched from 3x turboprop to 4x turbofan edit: had to correlate sources to find that a bunch of popular aviation blogs got the original design wrong. was actually 3x turbofan -> 4x turbofan

Everyone claiming you are wrong hasn't bothered to google. Literally the first response for "overture turboprop" is a series of articles confirming what you said. > The Overture supersonic aircraft will be powered by three turboprop engines, which includes two that will be mounted under each wing, while the third engine will be fitted at the end of the fuselage. https://www.aerospace-technology.com/projects/overture-…

It’s like claiming an upcoming Tesla model will use Ni-Cd batteries. No matter how many blogs claim it, it's clearly wrong.
