I'm actually surprised more airports don't have VIP level gates that the airlines can pay a premium for allowing them to charge a premium to their passengers. It'd be interesting to see where the price could be that would guarantee enough passengers willing to pay the premium for much reduced airport headaches.

There’s probably a classist risk to this (recall the uproar over the residential building in NYC that had separate entrances for different unit classes), let alone the logistics are needed at whole-airport level to support it which is difficult to retrofit.

My take is that they felt like they were already pushing their luck with the prototype and didn't want to scare investors away when it inevitably crashed. I share your skepticism, especially with their timeline. It has been some time since I looked at them closely, but they originally pitched developing their own supersonic capable turbofan to power their eventual production model. Especially with such a small team t…

Hah.... in the back of my mind: announce they're going to crash it before the fly it. "This flight we're validating our model by pushing the real world to the limit. It should explode about 38s into the test and crash. We've cleared the expected area"

Hopefully the plane is autonomous

Just build an entirely different terminal instead of shoeing it into the same building as the terminals for the plebes. Out of sight, out of mind.

The classist risk is already there with the pricing they have for first class seats. By making first class only planes, you can have economy only planes like Spirit. Then nobody would be complaining about first class since nobody would see first class. I see no downsides with this concept!

TLDR: We changed our plane design and lost range, we used ai in helping tweak our engine design to get back our range, we were successful in our computer models.

This article is just another from what are fundamentally hardware companies proclaiming how they're implementing "ai" and it's doing so much to help to gather more stock/venture investors but with no actual substance.

Everything he discusses taking into account are things that airplane/engine manufacturers already do and it doesn't require ai, just some python or god forbid, an excel sheet.

His statement about the relationship between airplane and engine manufacturers is factual correct but so blatantly wrong. You think GE/PW and Boeing/Airbus engineering don't work closely with each other when a new model is being developed? You think either would risk hundreds of millions and years of development without talking to each other? How does anyone take this guy seriously enough to give him millions of dollars?

"This close approach gave rise to mkBoom, our proprietary airplane design software. Initially created in a simpler form for XB-1, mkBoom has evolved significantly and is now pivotal to designing our Overture airliner."

This is the same overture airframe that supposedly had it's final design released in July of 2022? And was supposed to be rolled out in 2025? And have it's first commercial passengers in 2029? (Ref. 1)

But apparently 18 months ago the structure was being redesigned in such a way that caused a 1000 mile range loss (that is described as "subtle" fuselage change)? And in response to that last year they completely redesigned the engines and regained that 1000 miles of lost range... Sure.

More importantly, given the FAA states they a new aircraft takes 5-9 years to certify (Ref 2.) it seems the 2029 target is not viable any longer right? So are you going to tell American or should I?

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?". [0] https://en.wikipedia.org/wiki/Multidisciplinary_design_optim...

That doesn't sound good to investors that don't know anything and don't do any due diligence.

> At Boom, every engineer is expected to code and to leverage AI.

As an engineer I find "leveraging AI" to be a very troubling idea. I'd want to know detailed specifics of just what management believes AI should be used for before I accepted such a job.

As a passenger, I damn well don't want to fly on an airplane designed with software that can't count the number of bs in blueberry.

They keep calling this thing an "airliner." Assuming they ever go into production, they'll definitely sell some units to Saudi princes, but commercial airlines? Nope. Any customer that could afford a seat on this thing could afford to rent a Gulfstream and not have to share it with others.

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…

So they can script their design software then. In the modern era I'd consider this table stakes for any big engineering project.

What are they using, then?
