Well, the scope and scale is certainly impressive, and I imagine it costs about as much too… Lego should put out cheap sooty Falcon 9 kits with all pieces except payload having been previously used …

A classic medevac chopper:

Solar hot water is fairly easy, as long as you have something black and watertight. Wind generation requires less tech than solar PV, although concentrated solar thermal would be similar to wind, aside from steam handling. This assumes the sun is still shining, not blocked out by clouds. AFAIK, military industrial would be primary targets, with population centres being collateral damage. So most useful industry (not including useless consumer goods) would be wiped out.

From what I saw from pork chop plots, there are some times where the dV cost doubles or triples or more…

Okay, so a booster airframe has made 20 flights. Does it still have any of its original Merlins? What is the most flights for a Merlin engine?

Geez, it might have been back in the 80s or 90s (maybe later, but don’t think so) that I came across an article suggesting that the blocks that built the Pyramids were poured, based on inclusions like hair. But apparently the theory never gained traction at the time…

The Battlestar Galactica reboot was pretty good, and they took a more realistic approach to space battles, although it still seemed to somewhat degenerate into point-blank brawls…

You know, this is certainly a huge advertising/sponsorship opportunity for a business like that, preferably one with deeeeeep pockets

Would it not be simpler to just build a solid rocket motor into the base of the penetrator, to be ignited at the best point in the trajectory?

Yeah, the imgur community has not been kind about this. IMO he's not worthy of making the thread title.

Every cat's name is the sound of the cat food can being opened.

They certainly don't need camera software any more...

The biggest issue would be having the necessary resources, mainly fuels and ores, in economic reach. Can’t do much without iron ore and the coal (or oil?) to smelt it. Perhaps the most civilizing advancement would be electric light, but that would probably be too close to witchcraft…

You could add SpaceShipTwo to that first list. There are also the Dragon capsules to consider. I wonder how Dragon turnaround compares to Shuttle turnaround…
