https://youtu.be/TGO4LtCctTk?t=22 https://youtu.be/TGO4LtCctTk?t=22 Looks like a liquid-fuel rocket engine? Wow. That's got to be one heck of a hydraulic hammer when it hits 10,000g. What kind of rocket engine have they designed that could survive this? Obviously it's not going to be a conventional turbopump; those things have micron tolerances, no way those could withstand 10,000g and still work. Probably they're doing some kind of pressure-fed engine (the fuel tanks held at high pressure, probably by compressed helium). They don't seem to publicly answer these questions, anywhere on their website? That's credibility-hurting. There've been rocket engines built in the past that can survive low 100's of g's, at least. Those were exotic solid-fuel designs, intended as air-defense missiles. https://en.wikipedia.org/wiki/Sprint_(missile) https://en.wikipedia.org/wiki/Sprint_(missile)
