Could not get through the drm and tracking click through agreements on this site. Seems like there's no way to view this article without agreeing to be survieled for marketing purposes

JS off did the trick for me.

Heise had an interesting article the other day that immediately showed up just how bad they are: https://www.heise.de/en/news/Administrative-court-Cookie-ban...

I don't think that's the right article...

It is? Their cookie consent is way outside of the legal requirements that the article was reporting on.

Oh! When you said "They", I assumed you meant "The craft in the original article", not "cookies". My mistake!

This is not a new concept. You can see a discussion of this technique being used (to a degree) on battleships in WWII, by watching some of the videos on the Battleship New Jersey YouTube channel.

There’s also a Russian torpedo that uses a similar concept to “fly” at supersonic speeds underwater.

Supercavitation

Is it supercavitation or is it riding in a bubble of steam that it creates ahead of itself?

Either way, it’s effectively flying through the air bubble underwater, which was the concept I was thinking of.

This concept also seems related: https://en.wikipedia.org/wiki/Air_cavity_system
