Or you could say 6 787 engines, Or 6 General Electric Genx, Or 6 Rolls Royce Trent 1000 engines. Saying 747 is just trying to puff it up and make it look bigger.

So will the 5 Merlin's be Vac optimized?
If you're happy and you know it,
It's your med's!

At the end, only a new rocket (in the delta-ii, taurus ii range) more on the market place... but good for SpaceX to get one customer more which pays for R&D.

That's a 115m wingspan, gross weight of 545tonnes, needs a 3650m landing strip, and will carry an 223tonnes Falcon 9. Uses the Mojave Air and Space Port. And I still can't believe they have Mike Griffin on the board!

Seems like an ambitious project, I wish them good luck, but I wonder if it is really better than a ground launch.

Well it does get Elon his reusable first stage ...

I am not sure, those are stubby wings.  Reminds me of the OS Taurus.

What imcub meant is that the AIRPLANE is sort of a "first stage." ;)

I don't want to jinx it, but I thought "Spruce Goose" when I first saw it!

This plays to some of SpaceX's strengths... They know a lot about rocket manufacture, very little experience with launch operations (and they seem to want to get away from gov't launch sites).

Is there still a press conference at 11 PST?

I don't see any schedules on their site.

Don't you mean Pegasus? Taurus and Minotaur are ground-launched while Pegasus is airlaunched by a L-1011 Tristar.

Two interesting notes from the FAQ:
Q. When do you see the maiden flight of new launch aircraft taking place?
A. We are still in the planning stages but we expect to conduct flight testing beginning in 2016. The first flight will occur once
we are satisfied the system is ready.

and

Q. How many jobs will this program create?
A. There are already over 100 people assigned to this effort and we will see a significant ramp-up as we move deeper into the
engineering phase then start manufacturing and eventually operations. These jobs will first be located in Alabama, California and
Florida. We are proud that the headquarters for this effort are located in the Rocket City Huntsville, Alabama.

looks like a pegasus on steroids... not terribly revolutionary but I guess its a potential step in the right direction... baby step - certainly not anything ground breaking or far reaching... sigh...

Wonder what flavor of Merlin is on the Stratolaunch rocket. An uprated Merlin 1-D with more powerful turbo-pump and bigger exhaust nozzle perhaps.  Anyone care to estimate the thrust  and ISP for this Merlin variant. Really don't think the ground launched Merlin engine is optimized for air-launch at 30k feet.

I have to admit I'm slightly disappointed. It's a neat concept, but I had hoped the announcement would involve a new payload. We don't need more launch systems. We need more customers for our current launchers.

You are right, that is what I meant.

Yes they are playing rocket man.

It seems spaceX has found a solution to there 3rd launch site and the avaian (aviation) mass transport.

More like the fabled Spruce Moose that can carry passengers from the Belgian Congo to Idlewilde in a mere 17 minutes!

Or you could say 6 787 engines, Or 6 General Electric Genx, Or 6 Rolls Royce Trent 1000 engines. Saying 747 is just trying to puff it up and make it look bigger.

So will the 5 Merlin's be Vac optimized?

Maybe they are going to the find a few retired 747s in the desert, and salvage the engines.

Does this thing only launch a Dragon or a fairing that happens to be the same diameter as the core stage ? Kind of restricts the number of available payloads, right ?

A competitor with SKYLON except jet "first stage" launch platform does not need to go orbital only the payload. A great idea and the fact that the jet does not need to have a reentry profile is a big plus.
