So why is this thread tagged "stupid planes' anyway? Find out...tonight!

e of pi: So, I'm trying to figure out this whole suborbital thing.
Brainbin--gtalk: Well, good evening to you too!
e of pi: Sorry, yeah, good evening. How're you?
Brainbin--gtalk: Bored.
Did you know today is the first time Obama has been seen with coffee since he won the nomination?
I've only read it on the last ten sites I've gone to.
e of pi: It's a bit much, I know, you'll just have to excuse us. We’re full of hope, don’t you know?
Brainbin--gtalk: I tell you.
You'll NEVER see a Canadian PM be so image-obsessed.
e of pi: Of course not, you can only make a parka so stylish.
Brainbin--gtalk: Har har.
Okay, let's circle back round here.
What about this whole suborbital thing are you trying to figure out?
You seem to understand it better than most people.
e of pi: I'm just...trying to figure out what's going on with it. I mean, compared to orbit, it's just not _that_ hard, but it's been four years since the Xprize, and it's....super slow.
Have I linked yo uthe Futron study before?
Brainbin--gtalk: Is this the one with the diagrams?
e of pi: I think it's the other one:
http://www.spaceportassociates.com/pdf/tourism.pdf
Brainbin--gtalk: Oh right, the one that's 79 PAGES.
How could I forget.
e of pi: Sorry, page 10 of the PDF is the one I was thinking of.
The top graph on that page...and I guess the description of it at the bottom of page 9.
Brainbin--gtalk: Oh, a parabolic projection graph.
Funny how everyone predicts those things and they never seem to happen.
e of pi: "Suborbital space travel is a promising market — Futron's forecast for suborbital space travel projects that by 2021, over 15,000 passengers could be flying annually, representing revenues in excess of US$700 million"
I'm just trying to figure out with all that money on the table, why everyone's being so slow about it.
And then all the approaches are different, too.
Virgin's basically scaling up SpaceShipOne to make SpaceShipTwo, except that they unveiled it three years ago and they're only just now finalizing the design.

They've at rolled out White Knight Two, the carrier, but for having the space ship “60%” done in January I certainly haven’t seen much of it...
And then there’s the engine. I haven't seen anything on that since they blew one up on the stand a few years ago.
And then there's other people who aren't using a carrier at all.
XCOR's doing something smaller, like a little baby airplane with a rocket stuffed into it. They light it on the runway, and bam zap-straight to the moon.
Brainbin--gtalk: We've been over this, though.
We were supposed to have moon colonies by now.
Lost in Space was set in 1997. They were going to Alpha Centauri.
e of pi: Hey, we still might! Ares V is coming, and the latest Altair images look pretty slick.
Brainbin--gtalk: That would be nice.
Think of the advertising.

Brainbin--gtalk: Hey, there you go.
There's hope for you.
Futurama is back.
I mean, only in movie form, but still. They might make new episodes too.
e of pi: We can hope, we’re all doing this at Fox:
https://www.youtube.com/watch?v=8AOfbnGkuGc
e of pi: It'll be cool to see. Maybe we can get Firefly back too--BSG is getting all set up to go out with a bang--can’t wait for Season 4.5! Maybe Sci Fi can pick it up from Fox to fill the hole? Dr. Horrible was really awesome, you know?
Brainbin--gtalk: Argh.
Yes, of course, Dr. Horrible, the latest creation by the Great and Powerful Whedon, the greatest writer in the history of the English language including Shakespeare. Spare me, I get enough of that on TVTropes. You know, there is no possible way this Dollhouse show can POSSIBLY be as good as everyone is hoping it is, you know that, right?
e of pi: We'll see.
But then there's the whole thing with Rocketplane--you know, the other half of Kistler?
Brainbin--gtalk: So wait, is that suborbital too?
e of pi: It's confusing.
They're "Rocketplane Kistler," and the Kistler part is orbital, and supposed to go the the station.
Rocketplane is supposed to be...like, a Learjet with a rocket in the back. Take off like a plane, fly up to altitude like where Virgin drops their SpaceShips, and then light it and go to space.
It sounds easy, but they've been pretty quiet. Maybe they're just busy with the orbital stuff?
I don't know, it's just a lot of variables--drop-plane or no? Where do you light the rocket?
_What_ rocket? XCOR and Rocketplane are both liquids, but Virgin's a hybrid.
Brainbin--gtalk: So wait.
It flies into the stratosphere (probably higher, I know, but roll with me here) and THEN blasts off?
e of pi: Yeah.
Just like where SpaceShip one drops of the plane.
*off
Because it's suborbital, you need a lot less speed. Like, a fifth of the velocity of orbital.
So the speed you can get from a plane is actually helpful, and the height helps too.
It wouldn't matter if it was orbital, unless it was something like Skylon.
But jets are just way better than pure rockets.
More of what I don't get--XCOR takes off on rockets the whole way and loses that benefit.
I dunno. It just seems like it's all coming so slow, I wonder why? Are they just not spending enough, or is this really hard?
And I'm looking forward a lot to a year or three when they're all flying.
Brainbin--gtalk: Or five.
Or ten.
e of pi: I don't think it's _that_ hard.
...I should really stop ranting and focus on this physics writeup, but I just needed to figure this out.
Brainbin--gtalk: Not as hard as physics, anyway.
Shudder.
It's worse than that, it's physics, Jim!
e of pi: Oh, god. Do we want to have the trailer talk again?
Brainbin--gtalk: I will concede, as pleased as I am to see Kirk back in his rightful place as the one and only Captain of the Enterprise, I am not looking forward to the next trailer.
e of pi: I don't get why they're building the ship on the ground.
Is the SIF field on? Or what?
Spaceships belong in space.
I don't know, I'll probably go see it if it gets good reviews--I saw Nemesis in theaters.
Twice.
And that was NEM.
So...we’ll see.
I’d need a pretty good reason, I think.
