I think some aspects of it are still classified so that's why you can't get that last part.

Now that's an interesting thought......what could be classified about a BDB using pressure fed engines?
May not be classified, just restricted by ITAR. Technical information on how to build a big, powerful rocket simply and inexpensively sounds like just the thing that the US Government would rather not have widely promulgated.

And ITAR rules are so amorphous and vague and badly-interpreted that it could turn out that there is NOTHING sensitive in there, but somebody thinks there might be and so they don't release it.

Heck, about 18 months ago I was in a briefing about future planetary exploration spacecraft concepts and somebody was showing some PowerPoint slides about a balloon for exploring Titan. Nothing exotic about this at all--it's essentially a hot-air balloon with the heat provided by an RTG (plutonium battery). But somebody noted that one of the slides had a dimension for the balloon (about 40 feet in diameter) and suggested in all seriousness that it was probably protected by ITAR.  (Easy to fix: the guy opened his PP file and deleted the dimension).

Yeah, we have to keep the North Koreans from building hot-air ballons for Titan.

Ah, ITAR, the gift that just keeps on giving.  ::)

Had a small picture of a foam, no detail, mockup slip out into the wild and the $hit hit the fan.  Never mind that high res screen shots of the 3D model and video have been publicly released.  I've heard of things as simple as Magpul magazines being ITAR restricted- when anybody can walk into a gun shop anywhere in the US and buy them right off the shelf no questions asked.

NTRS can only release what they actually *have.* It could be that they simply don't have a copy of Volume II to scan and release. Or it got lost in the bureaucracy.

Excellent job. I suspended my disbelief in ten-seconds. You sold the concept!

Impressive video. The Apollo CM looks amusingly tiny perched atop that monster.

Nice video, but some odd  changes were made from the actual Aerojet design.

Really impressive. We should not forget to thank to maker of this video: Hazegrayart. His videos are just amazing (please look into his YouTube-Channel!) B)

Ok, a stupid question, but one that's been bothering me ever since I learned of the Sea Dragon.
If the Sea Dragon is floating in the ocean, filled with cryogenic propellants, why doesn't it turn into a giant, floating ice cube? After all, we've all seen pictures and videos of Saturns and Atlases covered in ice before and during launch . . .

cheers,
           Robin.

there will be a ice sheet on Sea Dragon, but once that Monster take off, it will rain pieces of ice down into ocean

I Notice that too, i wonder what for documentation use Hazegrayart to render this Sea Dragon

Yeah the video author made some changes to the design. Still, the underwater ignition is awesome. Looks as if a tactical nuke exploded underwater  :o
