Interesting that this is slower that the Concord which cruised at Mach 2. I wonder if a slightly lower speed makes the economics more sustainable.

Boom were previously targeted a cruising speed of Mach 2.2, I wonder why they lowered it to Mach 1.7 with the latest design update. Might be related selecting an engine. The previous version of the design had a fantasy engine that didn't exist (I think the specs came from a military engine that they couldn't use due to export restrictions), but now they are working with Rolls-Royce, and appear to have actually select…

To me that sounds like a fuel saving option. Might extend the routes.

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…

This is not a winning proposition. Even if we presume these will fly from a VIP terminal so the time you spend at an airport is low, you still need to get there. I just can't see everyone being flown in and out on a helicopter but maybe my imagination is stunted. Once you begin to add up those hours, you are just not saving enough time for the surely astronomical cost. You'd need a much longer range for this to be a…

You are arguing with a straw man. Nobody said driving to the airport will change. The claim is for the price of business class, get there in half the time.

Not a lot to go on here. Boom projects first flight in 2026 for the Overture. They seem to be fairly close to first flight with their XB-1, but it has not flown yet. I congratulate them on getting funding, but all the hard parts are ahead. https://en.wikipedia.org/wiki/Boom_XB-1

They still don't have an engine that allows them to fly supersonic...

Shaving off enough hours to be able to board a plane in the early morning, have a two hour business meeting in the destination and fly back and arrive home in the late evening of the same day is a huge draw to some.

At just under 5 it already is, I know a few people who do it. Hawaii is a bad example because its very much a leisure market. They can barely make business class work with recliners let alone a Concorde replacement. That’s why they put their worst business class on the route. This will end up running LAX-JFK-LHR in my opinion.

Would they be allowed to go supersonic for LAX-JFK?

No, that route is over land.

Why would you assume this aircraft wouldn't have a luxurious cabin? It looks pretty nice from the one rendering they have on the site. 1-1 seating, so direct aisle access for all. Plenty of room.

Renders of any new aircraft always show them full of bars, gyms, bowling alleys etc, but the reality is just as many seats crammed in as they can fit, and then some.

They are targeting business class passengers, which makes sense. Supersonic is not going to make the profits off the Ryanair set.

I wonder how noisy they are even sub-sonic. Concorde was so loud on takeoff and approach, you'd stop and look up even living ~20 miles away from Heathrow. If you tried to introduce that now, there's no way would it be accepted.

Old jet engines are super noisy. Modern jet engines are much much quieter.

What makes the newer engines so much quieter?

Plus a significant impact of Concorde was the (very turbulent) flow from the reheat; from memory it's not really dissimilar to many modern military aircraft with reheat today.

They'll get a fair gain from just not having reheat, yet alone the rest of the benefit of decades of aerodynamic design around engine exhaust flows.

CLE-MUC also has about 1/3 of the route over land, which you’d have to fly subsonic.
