Did it take the Blue Spruce route and stop in Greenland and Iceland?

Portland, ME to Azores then on to Valencia, Spain. They also do trips from Texas to Brazil and Spain to Brazil. Long flights solo so the pay should be pretty good.

And here is some fresh evidence the whole E-VTOL pyramid might be about to come crashing down. This Aviation Week article is free to any/everyone until Feb 4th:

> **[Airbus Helicopters To Pause CityAirbus NextGen Development | Aviation Week...](https://aviationweek.com/aerospace/advanced-air-mobility/airbus-helicopters-pause-cityairbus-nextgen-development)**
>
> Even said a strategic review of the program concluded that battery technology had not yet evolved to meet the minimum level of performance.

When no less an authority than Airbus says the energy density of battery tech won’t support E-VTOL development for a long time, if ever, I tend to believe them.

The various small start-up operators are mostly operating on the basis of not yet knowing all that they don’t know. Plus some of that famous techbro/IPO hype. Airbus has neither of those motivations / handicaps.

Airbus is also sorta famous for pursuing engineering do-able tech well past the point the business case works. A380, their role in Ariane, a couple of their helicopters over the years, A400M, etc. If they’re folding their cards now, that’s IMO a strong vote of non-confidence.

I _believe_ with less than full confidence that the lede isn’t quite true. Boom did exceed Mach 1 but they are not the first such deliberate reusable civil flight. OTOH, the events I’m thinking of may have occurred out over the ocean, albeit still under US jurisdiction. That may be the quibble that keeps the lede strictly true.

In any case it is indeed a significant accomplishment in aviation history and deserves its spot in the record books. And Boom & their people deservs a lot of attaboys for getting this far despite several major configuration & powerplant iterations. Lotta wannabes have died of cash shortages long before getting even this far.

If “civil” isn’t being given a special definition, the Concorde was a supersonic cruise civil aircraft. As would have been the Concordski, if you allow that “civil” aviation is still civil aviation even if the developing and operating agency is an organ of the state, in true Socialist fashion.

Oops. Poor bastard.

It is inherently very dangerous out there and it only remains as safe as it is if everyone is playing heads-up ball all day every day.

The APU (Auxiliary Power Unit) is back there aft of the pressure bulkhead. So a small jet engine with an attached electrical generator and a (very) hot bleed air tap-off. And a fuel supply and a fuel pump. On a typical flight it’s shut down after the second engine start, and left off until a minute or two before parking. But there are legit use cases to leave it running gate to gate and throughout the flight. So depending on where they were in the post-pushback, pre-takeoff process odds favor it having been off. OTOH, if it was the fire origin, it’d have had to be on.

The other plausible sources of fire “near the tail” are the aft galley or lavatories. Either electrical problems or an oven or trash fire.

We can see the fuselage roof is heavily damaged and there’s a fire raging inside the _forward_ cabin. Which to me suggests the origin was inside the pressure hull and inside the cabin, not outside the pressure hull where the APU lives.

A fire in the cargo compartments is another possibility. But we don’t see those doors open, nor do we see evidence of damage below the waistline.

Based on noting beyond that picture and the terse bit of maybe-reliable article text, I’m going to say a cabin interior fire with so-far indeterminate origins. And I have low confidence it actually started “near the tail”.

  

I’m a doctor, not a magician, Jim! This one’s a write-off.

Granted. But the claim was this was the first civil supersonic flight _over the US landmass_. Concorde was certainly capable of that feat decades ago. But it wasn’t legal and they didn’t ever actually do it. Boom had the waiver to do it as a test flight, and did it.

From the ABC News story about the ramp worker fatally struck by a vehicle:

Is it weird that I’m kind of impressed that the reporter didn’t use “tarmac”?

I was impressed too. Perhaps the reporter was simply plagiarizing whatever the airline’s or airport’s press spokesman had said. The fact they quoted the official FAA definition of “apron” suggest the reporter didn’t know what it meant and so looked it up. IOW, the reporter expected “tarmac” and when they didn’t get it, they were confused.

IME “ramp” is pretty much the standard US term within the industry. “Apron” is a legit official US ICAO term but has a decidedly foreign feel here. You do see & hear it used in non-US countries a bunch.

“This doesn’t go beyond the [whatever]” doesn’t ring a bell no matter what we stick in there. Other than maybe “bar tonight”. That fits great in _any_ context involving secrecy amongst goof-ups.

Likely true for “landmass”, though the Global 7500 FTV5 was probably still in US territory, off the coast of California when it broke the sound barrier.

Given as this plane wasn’t at all designed for supersonic flight (and it still won’t be when upgrades rebrand it to 8000) that’s a pretty cool feat for a civil aircraft.

It’s pretty neat for Boom, too. Curious to see how successful that program will be.
