> XB-1 is the world’s first independently-developed supersonic jet, breaking the sound barrier for the first time in January, 2025. It was designed, built, and flown successfully by a team of just 50 people This is a great headline and very impressive. However, it’s also somewhat puzzling to see the company spend so much investment money to build a small prototype plane that doesn’t resemble a commercial airliner in…

The market for Boom is not commercial passenger flights. So much time is wasted with security, boarding, taxi-ing, waiting at the destination for a gate to unload, etc. that the flight speed is not a big deal. Existing commercial passenger jets could already go faster without going supersonic and save some time, but it doesn't matter. Even if you fly commercial passenger jets at the absolutely face-melting Mach 3.3 o…

Not disagreeing with you at all.

What is the market for Boom?

> We can literally define an airplane parametrically in a configuration file and press a button. In a matter of minutes we have a complete quick-and-dirty analysis of how the whole aircraft performs—as mkBoom flies the aircraft through a full simulated mission (takeoff, climbout, acceleration, cruise, descent, landing). Overnight, mkBoom can run higher-fidelity simulations for a more exact understanding of performanc…

Boom’s potential customers wouldn’t be able to put more seats on their planes even if they want to. I suppose the targeted performance affords very little margin for customization

> Together with a few other optimizations, these tweaks yielded over 1,000mi in increased range—enough that we could now afford a remarkable passenger cabin without sacrificing fuel efficiency or range. Honestly, the way the narrative reads, they're still sacrificing 1,000mi of range in the interests of an improved cabin experience. They've just found an optimisation that enables them to reach a net neutral state. Gi…

Saw a Jet Blue plane wrapped in Peacock livery today… selling the planes themselves as billboards sure does feel like scraping the bottom of the revenue barrel.

It might be a fad, but the current trend in US public aviation is increasing premium cabins and premium revenue: https://simpleflying.com/why-us-carriers-doubling-down-premi... This is the reason Delta and United and doing well right now and Southwest and the LCCs are struggling. It wasn't true just a few years ago, but if this continues as a trend, I could see an airline sacrificing fuel efficiency for a dramaticall…

Premium cabins tend to be a very small proportion of overall seats and are about overcharging for a little extra legroom and service rather than trading off operational flexibility for unique luxury though. Big difference between charging 3x economy rates for 2x the space for a carefully estimated proportion of seats in a mixed configuration (no brainer) and hoping your layout is so good it justifies thirstier, less…

Business Class trades well above 3X tourist class.

If you are a tourist searching business class on Google Flights, of course it’s 5-6x more expensive.

True business class / upper class travelers get discounts of 20-50% for J. And no, they’re not using Amex/Chase Travel.

That would be an accurate statement if they were being sold for bottom of the barrel prices.

> Premium cabins tend to be a very small proportion of overall seats Most of the profit on a plane is made in business class. If airlines could fly an all-business configuration, they would. The problem is the smallest planes that can do high-paying routes like LON-NYC are bigger than that customer set. So the airline throws in economy seats, often barely breaking even on those, to fill space. In a world with small a…

Another factor in this mix is frequency, which matters a lot, especially to business travellers.

A once-daily supersonic flight might minimize “time in the air” while a once hourly mostly-economy 737 shuttle minimises “time away from home.”

AKA they're doing what every other aerospace company has been doing for decades, multidisciplinary design analysis and optimization [0] with simulation in the loop. If you were to ask them how they're leveraging Design of Experiments I bet it'd be met with "design of what?".

To be fair, modern airliners, even budget ones, are way more comfortable than Concorde. You can visit one in a museum, it's very cramped, and noisier. Concorde had way better service tho.

Looks like investors and potential employees are asking if Boom is fast growth tech company and this seems like a lame attempt to make up an answer instead of saying- we're solving a different problem on a different timeline. Can't imagine Elon writing something like this 10 years ago.
