"Oh, quick note: the first stage splashes down off the coast and is recovered that way. Propulsive landing is complex and unlikely to be efficient for a small-lift vehicle. Don't know why I didn't say that in the video. And when I say launch anywhere, it's obviously within reason. No spaceports in Central Park." Limited entirely to coastal locations? Curious about whether you see helicopter catches or landing in large purpose built freshwater pools (to avoid saltwater necessitating more refurbishment. Requires guidance system through re-entry though) as viable alternatives?

I'm really very surprised you've never mentioned Beal Aerospace (1997-2000) and the Beal BA-2 which was in many ways a classic pressure-fed "Big Dumb Booster" with 17 metric tons to LEO. The kerolox BA-810 engine reached the test stand in a full-scale configuration and produced 3.6 MN (809,000 lbf) of thrust.

I’m a bit confused. If you’re having it splash down in coast and therefore i assume also using a boat for recovery, doesn’t that kinda defeat the point of the pop-up? Why not just go all way and have it land further downrange, and save yourself the pop-up payload hit?

Why doesent pop up require downrange clearance? The range clearance seems to be more for "in case of failure" than "stage falls here". With pop up you will still have potential for falling second stages downrange, but you also expose yourself to failures that drop stages in basically any direction during the pop up, giving you a large circular exclusion zone around the launch site, not just a cone as we see with normal flights.

​​​@@SpaceAdvocate nothing they said was wrong. It was the first flight that nominally reached all its objectives( the fourth attemp at those objectives), but a very marginal success. "Gathered a lot of data" is just stan excuse for "we don't know what we are doing and got lucky this time". Their design was obviously rubbish. "Nominal orbital insertion" is just BS, the flight was suborbital and always planned to be, there was no "orbital insertion". And there's a plausible leak of SH exploding during or shortly after splashdown. Not that great either.

@@sdem9 The trajectory was intentionally slightly suborbital, but it's really just a technicality. It has no practical significance to the accomplishment. If Starship had pointed the engines slightly differently during the ascent, it would have been in orbit. And mattkingston did say things that were at the bare minimum misleading, if you accept they weren't directly wrong. For one thing - the Mir space station did not perform a soft splashdown, while the Starship stages did. His statement that they were similar events is false, as far as I am concerned. And it's false that it is a failure when it succeeded. As for the Super Heavy exploding - that was not unexpected. It was thought that the stage *might* survive toppling over into the water, but clearly the force of the top of the booster slamming ~70 meters into the water imparted too much force on the vehicle. If it had survived, they would have had to open up on it with a .50 cal or something, to get it to sink, so the explosion saved them some trouble.

Seeing your most recent video, why not just buy some Scuds or similar (somehow, maybe ask Yemen they need cash) and stick them together with explosive bolts lol? You only need to make the guidance system then, which you could use a smartphone and write a program for it. I'm joking of course and it would suck compared to your design but it'd be funny if someone made that actually work, it'd be the most "that'll do" thing in the world.

So building a rocket engine is actually quite hard, because you REALLY get into machining. Starting with really small engines and working the thrust up might be a good approach. Also, in the early stages the LOX is a real problem, when you're on a budget. My approach would be LOX making from scratch, because in the process you learn a ton about propellant management, system design, safety hazards and most important of all, manufacturing. I wish you the best of luck!!!
