From today's news.

Apparently this morning JAL is in for $10MM to sit at the table, it's a drop in the bucket I know.

Commercial? Tupelov then Concorde , A380, 787, 777, then 880, 747

Passenger plane? Citation X+/X slot in 3rd/4th, with Falcon 7X, Bombardier Global 6000, Falcon 900X right behind the 380.

But data sources vary.

I have my doubts. Much of the team is from Adam aircraft whose A500 was dramatically overweight and ultimately led the company into bankruptcy.

I think that ahead of the Airbus and Boeings you need to consider the TU154 and the VC10. Generally the more modern large passenger planes are much slower than the 1950's designs primarily for fuel efficency.

It's TupOLEv guys, not TupeELOv.

In normal operation I think 747 would be marginally faster than other modern jets, don't know how A380 Mmo is.

Anyway I would love to see the Boom fly, but I see the real chance for this to be essentially zero. They'd need much, much more money to build the aircraft than they seem to have.

Operation wise, if they could make it work at business class fare level, I think it could make sense. For LON-NYC surely, if you can make same-day return, you are saving hundreds in hotel costs only.
If a company would wise up enough to consider travel downtime, it could work out to be a good deal.
Especially if the Boom can also go trans-pacific.

Unquestionably the VC10. In military use with the RAF, during the Gulf War, a friend of mine experienced some extremely fast journeys back to UK to pick up the next load. From another forum back then ...

I wish Boom well and I would love to see the aircraft fly.

Boom says it will cruise at Mach 2.2 which is faster than Concorde, however as far as I can see the Boom will not supercruise which I assume means it will need to use afterburners which I suspect will limit its range despite what they say about range. I would like to know more about how they have calculated its range.

Lack of range was a problem for Concorde the AF Concordes were apparently often near fuel minimums when going to NY

The F-22 can supercruise so maybe with the right combination of engines and aerodynamics, the Boom will too.

Lots of different data out there, especially for older planes. And cruise, max cruise, design speed, etc., can mix things up.

A380 - cruise speed: 560mph, max design speed:635mph. I believe a VC10 was 580mph. So an A380 can fly faster, but flies slower for economic reasons. Which one is "faster"?

(In actual design language, A380 max design speed is Mach 0.96)

Rolls-Royce has pulled out as the engine supplier.With GE being stuck with $32M in unpaid work by bankrupt Aerion, finding an engine for the latest “new Concorde” will be a challenge.

Boom claims they’re still on schedule for 2026 flight.

No problem - Concorde didn’t take more than a few years to go from no engine to first flight, right? And Boom’s “and will fly late next year” from 2016 was delivered on time. Right?

- May 2022. Oops.


I’m sticking with my initial skepticism.

Now complete PPT?

Maybe Mig 25? You used to be able to buy that plane on the second-hand market as a plain folk from Ukraine/Russia, which might be justifiable for it to be a passenger plane.
