#22How big are the sonic booms gonna be?
At that height it doesn't matter IMO.

I guess it will be called rocket lag :)

#24Musk says the ticket price would equal an economy international plane ticket.
Back of the envelope calculation more or less confirming that here: https://news.ycombinator.com/item?id=15362976

#25So that's basically the first privately-owned ICBM?
No, the current SpaceX rockets are ICBM enough. This is much harder - ICBM's don't need to land at ~0 m/s vertical speed, and if they carry nuclear warheads (are there conventional ICBMs at all?) they don't need ~1 m landing precision.

A terrible idea, as the risk of accidental nuclear war is far too high. There's no way to tell if an ICBM launch is conventional or nuclear.

#26Interesting. Two little issues: safety and ticket costs. Also, your average overweight tourist isn't going to be very happy at several G's.
Extrapolating very naively from SpaceX prices[1] for Falcon Heavy to low earth orbit suggests a ticket price of about $150,000, at $1500 per kg That is ignoring safety, and other pros and cons such as Falcon Heavy didn't fly yet, Space-X doesn't have a passenger module, frequency and economic scale of passenger operation, different flight profile from LEO, lack of regulatory framework, and so on [1] http://www.spacex…
"About the same as full fare economy" So in the low thousands. Incredible if true.

#27I'm not sure here, but I think weather could play a major role in disrupting launches, greater than with jet liners, right? And not just due to windy conditions (which planes can better withstand up to a certain point), but also rough waters.
Another issue is noise. I don't see rockets happening that close to shore in large cities. A long pad-to-city commute, with ship trip included, would be another inconvenience.

#28BFR, Big Freaking Rocket?
The tame version is Big Falcon Rocket.

#29I wonder if they can compete with Boom Supersonic [https://boomsupersonic.com/] at the fuel cost. One reason Concorde failed was NOISE and FUEL COSTS.

#30I am sure mil would love this tech
