Wikipedia notes that a 1/3 scale Boom demonstrator plane is expected to begin flight testing in 2021. Otherwise, it sounds like they've produced zero planes that actually fly so far. Even the hype-ridden article admits that their founder/CEO has zero experience delivering real-world physical products.

Then there's the huge "SPACEX KILLER" banner at the top of that article...which has zero logic behind it, and is followed up by zero meaningful mentions of SpaceX in the article's text.

I'm sensing a really fawning fan-boy (writing the article), and/or a company that's absolutely desperate for credibility.

And the whole thing is full of factual errors as well. I’m not in aviation, but I’m quite interested in it and I know enough to get the sense that the only research this article was based on was some notes taken during a drunk hyperbolic conversation with the founder in a bar.

Confession - once the article opened by comparing a 250MPH Tesla (maybe true, for short periods, in a few extreme-high-end models, on certain test tracks) to Boom's 1000MPH+ speed (which all their products will need to routinely & economically sustain, in the real world), I stopped caring whether the article's "facts" were true or not.

If somebody is telling me that their radical new physics theory is true "because I'm an assistant examiner in the Swiss Patent Office, just like Albert Einstein was..." - then I don't see much point in fact-checking their Swiss Patent Office employment claim.

Pretty sure at one point that demonstrator was supposed to fly in 2019 if I remember correctly.

The same kind of delay for the main plane would put it close to 2030.
