The earth-to-earth idea is nice, and whilst it would be an improvement, I expect the travelling time to be the biggest obstacle. You have to gather the people, check them in and clear them during internation flights. Then you have to load everybody on a boat, ship them to the platform X miles into sea, unload them, take them up the big tower, letting them board and settle and depending on how predicatable this is, wa…

At the moment there's lots of time wasted walking to some gate at the far end of a massive airport. There's only one company here and one or two flights that go straight up and don't need to taxi. So the travel time in the boat won't be much more than the walk from the terminal to the gate.

Possibly, but decreasing the flight time still won't take much out of the equation that would make it a net win against normal aircrafts.

That's not saying there is no market for something like this, but for anything but the longest flights it's going to be a very specific kind of customer.

Umm was I the only one too assume that BFR meant Big Feckin' Rocket? Oh, no, I see waitbutwhy has a piece on it [0] I disappointingly see F is for Falcon, but still I really like the lack of marketing in the name. Plus I like the parallel with Roald Dahl's BFG. [0]: https://waitbutwhy.com/2016/09/spacexs-big-fking-rocket-the-...

I was under the impression that for quite a few people, possibly including the people at SpaceX, the 'F' doesn't stand for Falcon or Friendly or Fantastic or ...

This is not new. Cisco made a big router (BFR) and also a huge router (HFR). Among their designers, the 'F' did not stand for 'fast'.

Out of five vehicles built, two have been lost. I think you can find sources on those two incidents easily enough.

According to wikipedia, there were 135 shuttle missions. So, a 1.481% failure rate in case anyone was wondering.

From a commercial, ROI standpoint, having %40 of your hardware eventually destroy itself is bad news. Especially since each time your whole enterprise stops for years until you find out what went wrong and fix it.

Look, you can't complain about government inefficiency like you can complain about corporate inefficiency because you are granted real power over the government by way of the constitution. If you don't want the space agency to be controlled by corporations not owned by Musk you can do something about it via the many channels that exist for that explicit purpose.

First of all I'm not american. Second, the US was not created democratically. With a corporation I can just not use their product, they don't get my money and beyond that I don't really care what goals they have in space. > If you don't want the space agency to be controlled by corporations not owned by Musk you can do something about it via the many channels that exist for that explicit purpose. Like what channels?…

Once the BFR starts flying and putting comparable-sized payloads into space for 1/100 the cost, I imagine there will finally be enough public protest to shut the SLS project down.

Making life multiplanetary seems like one of the least important issues of our times to me: either we figure out how to make life on earth sustainable in the medium term (next 50-100 years) or we do not have enough time to become multiplanetary anyway (since that will take centuries, and we will likely never leave the solar system anyway). So it seems a bit premature to concern yourself with interplanetary ambitions…

One thing Musk didn't mention (I don't know why) is that the BFR would make asteroid mining and outer-space manufacturing far more practical, and that could help save the environment.

You kidding? There's no way I'm staying in my seat during zero gravity. I might pay more to do a couple of extra orbits and play around before coming down.

I reckon everyone would be out of their seats as soon as boost is done. Getting everyone back into their seats in time for re-entry might be the issue ("take the nearest available"). Earth to earth flights would be sub-orbital though, so no opportunity for extra orbits.

I'm gonna miss the ding of the seatbelt sign.

Totally. Because NASA, ESA, and others use public money there was less (or little to no) incentive to strive for reusability.

Well, NASA had the right initial idea with the Shuttle, it just that their execution and then evolution of the idea was a total disaster.

To frame in a comment we often hear around here: if you don't control your funding, you don't control your destiny.

Building anything for the US government that's big enough and has potential military applications is virtually inviting them (and the large project procurement morass they bring) to become involved.

So the key takeaway for me today compared to 1 year ago, is that Elon has put a lot of thought on how to make this plan economically viable compared to just the vision last year. Multiple potential streams of revenue: - Government/intragovernment contracts to cleanup space debris. - Government/Private satellite launches. - Earth to earth transportation which Elon announced on Instagram that the cost would be comparab…

The other major thing was that companies could launch much bigger satellites where Space X would have no competition

I'd be curious how many large diameter applications there are. Physically-contrained uses (mirrors & EM dishes), but do those make up that much of the market? And does it make that much of a difference?

"You want to be inspired by things. You want to wake up in the morning and think the future is going to be great. That's what being a spacefaring civilization is all about. It's about believing in the future and believing the future will be better than the past. And I can't think of anything more exciting than being out there among the stars. "

We need people like this running for office. Not Elon specifically, politics would only get in his way, but inspiring yet pragmatic visionaries... willing to make mistakes, challenge common beliefs, and build the future.

For sure.

The problem....the ancient problem...is that the kinds of mental makeup that would be very good at running large organizations tend to also not WANT to do such things.
