here we go

[Nightside]

And we're off!

He's nervous, but he seems to loosen up a bit when he is rattling off numbers, and watching his rockets land!

Whoa... I didn't realize Falcon 1 was that big!

refueling

[Mitchz95]

The ship has two sea-level engines and four vacuum engines.

[Rakaydos]

"That's not a typo.

... though it is aspirational.'

[Mitchz95]

Construction of BFR starts in "about 6-9 months".

[DVDRW]

Year 2022 BFT cargo missions to Mars 

 

[Mitchz95]

Showed off a vid of BFR taking people on long-distance trips around Earth.

Looks like the presentation is over. No Q/A session, which is probably a good thing...

I think a fair number of people would not really want to take the kind of g-loading involved in suborbital flight.

[tater]

Volume he said was like A380. In economy config, that can hold over 800 people.

Well, I'm gonna be grinning like an idiot for a while now.

It's certified for that, but nobody flies them with that many seats.

[.50calBMG]

And be honest, how many of you are already building this thing?

I think a fair number of people would want to ride this machine, regardless.

No one would want to be on a flight from LAX to Dubai for that long... but who cares what the seat is like when the flight is under 30 minutes?

Typical 1 way 1st class is around 12k$. With 800+ seats, that's over 10 million $ a flight at current 1st class rates.

[Rakaydos]

Also keep in mind, every one of those "commercial terminals" for point to point transport is fully capable of sending people to earth orbit.

Considering the g loads you would experience, many people would care

And i think high g loads are a big bonus...

Well, there is that.

How many people ride roller coasters or the g sling-shots?

Similar loads (up to 5-6g).

On your back in a proper seat....not a problem.

Some folks will black out.
