#142Aren't supersonic jets more affordable? I mean I know SpaceX is about changing the world, and I know SpaceX is about rockets, but in terms of market, I think having a new Concorde would better fit the idea of earth to earth travel. I like how SpaceX innovates, but I think this is a "too soon", bad product idea because it will be too expensive at first, and supersonic jets would be a better competitor. Although I have…
Supersonic jets could - maybe - more affordable, but they are slower than rockets, and the value proposition is in speed.
I'd actually worry about crowding skies above the planet. A rocket flying with suborbital speed has arguably less means to avoid collision if the possibility is detected in flight. Also rockets will need to pass heights where lots of satellites, orbital debris and even charged particles can present some danger to flying objects.

> Aren't supersonic jets more affordable?
They're currently unavailable at any price. If you make a really wild speculation based on taking the price of the most expensive airliner Airbus or Boeing sells and extrapolating from there how much a supersonic one might cost, it's not obvious that the airliner is cheaper.

Fuel cost is a constant for rocketry, there is nothing to figure out there, and people tend to go through a whole bunch of checks before they are allowed to be flown on a rocket to stop them from developing some critical issue in a place where there is no way to get help or be helped. You can't do emergency medical stuff while accelerating and decelerating in a rocket and this one is doing either one almost all the t…
Ah the total trip time is at most an hour. People have been stuck longer inside NYC subway. Also on most trans-atlantic flight emegency medical diversion can easily take more than an hour.
Yes, but you're at 1G during that time. Big difference.

#145It's not like people will be able to reach their destination within an hour of booking their ticket. These flights will probably occur once or twice a day, which kind of defeats the purpose?
Regular intercontinental flights have the same problem. With transport this fast, you could theoretically fly in the morning, have a full day of meetings, and be home by the evening. With regular flights you'd spend a full day traveling both ways
Fair enough. In the meantime, I'll stick to Skype.

By a hell of a lot – concorde is an order of magnitude slower than the spacex solution claims to be, only ~2000km/h

These are very short duration flights aka ~35 min from EU to Japan. So you can predict anything in their path before it's an issue.
Also, you can design flight paths so they never intersect unlike aircraft that need to deal with weather.

I think that depends on whether or not the ticket is something like 50x more expensive. If Musk is proposing this idea then I assume it won't be too expensive, even for rich people. So it should cost significantly less than what private jet trip costs them (because the BFR is not so private after all). Of course, the faster time to destination should also balance things out, but I have a feeling a trip would be more…
Latest claim: "elonmusk Fly to most places on Earth in under 30 mins and anywhere in under 60. Cost per seat should be about the same as full fare economy in an aircraft. Forgot to mention that." https://www.instagram.com/p/BZnVfWxgdLe/ What's a NYC to SHA full fare one way, about $800? I wonder if he is also getting into the fuel business? So if this rocket holds 200 people, that only gives him $160k in revenue. Fue…
Baseless hype from Elon Musk!? How dare you! He would never do that...

Really? I'm surprised. Well then...
Re: SpaceX BFR [video]
#150I think if we measure the travel time from door to door the benefits of the fast rocket shrink in a relation to where is located. With airplanes this is solved, by the big infrastructure ( cities sometimes have even 2-3 airports ). Where I live ( Berlin ) with a flight to NYC would look like : 1. City center -> TXL - 20m 2. Check-in / security - 30m ( no joke, the airport is small ) 3. Flight - 9h 15m 4. Check-out /…
The reason the video shows a sea launch is that you can use a high-speed ferry to get to an empty area from the city center in less than an hour. Inland cities like Berlin aren't targeted.
