Agreed. I thought maybe these were newly published photos that had been held back from the public for a few months, but I've seen at least some of them before.

Launch loops can be built without any unobtainium. Though it is still in government-funded territory.
Space elevators might have a higher cool factor than a launch loop, but I don't think it's going to be even theoretically cheaper by any significant amount compared to a launch loop. And a launch loop is still pretty cool.

It's an interesting idea, but holy crap did you read the Wiki page on launch loops? [wikipedia.org]
It would have to be 2000km long. That would be a little bit pricey. And it would have to be built over the ocean because the momentum of the thing if it breaks would be equivalent to a nuke going off. I hate to go all George Carlin, but Not In My Back Yard.

A rough estimate [launchloop.com] (pdf link to presentation slides, estimates towards end) puts it around $10 billion for a small system, and $30 billion for a larger one. Add on an order of magnitude to the price for government waste, and it's still pretty good. Better than the most optimistic estimates for a space elevator, and way better than rockets.
Building over an ocean (or rather, starting from an uninhabited island and extending over the ocean) isn't really a big deal. Baker Island [wikipedia.org] will do as long as we can deal with the pesky environmentalists trying to save its status as a wildlife refuge.

These costs estimates are not meaningful (Score:4, Interesting)
Cost estimates for things that have never been build are not reliable. Your $30 billion number seems . . . conservative. Seriously, this is a large, dynamic structure. They don't really know how they'd put it in place. They don't know how they would confine the ribbon, or how reliable that system would be. With so many unknowns, you're really just pulling numbers out of your ass. Moreover, the odds that it is actually build-able are not great. The odds of it staying up for any usable period of time are much worse.

You know, this is precisely the reason there are so few private companies doing this. People expect miracles, and when the miracles don't happen the public loses interest.
Yes, we need to invest more heavily in advanced propulsion concepts. However, we don't currently have any private manned platforms based on *conventional* propulsion, so how could you possibly expect this? You could never raise enough venture capital to do anything other than conventional craft, because the risks are huge enough as-is. That will hopefully change in the future, but people need to prove that this is even feasible first. The Virgin Galactic team is going a long way to demonstrating this, and they should be commended for it. And this is all you have to say? Seriously?

You've no doubt seen metal production aircraft and over-paperworked metal and unobtanium space ships being assembled.

I suspect that these companies could afford to blow up dozens of vehicles and still come in under a NASA budget. Meanwhile, they've learned volumes from each real-world test, instead of hinging the whole program on years of theory and simulation.

Those boxes are weight... About 15 years back I helped build a very ez [wikipedia.org] (Rutan's design too, btw). Construction was 'composite' materials - a bit of a radical chance from the way folks traditional built aircraft. You cut a lot of foam and put fiberglass and resin on it. The real work was making the jigs to get the right camber on the wings. You had to put weight on stuff to make sure it warped at the correct angle. With some parts, you had to do large chunks in one laying (is that even the right word?) of resin since it makes a stronger bond.

These pictures speak volumes... (Score:3, Interesting)
Those MotherShip pics are scary. For one, the work areas are very cluttered which could lead to confusion, errors, rework and overall inefficiency. It appears there is no system in place to ensure that all tools and support equipment are properly accounted for and not left in the ship. This could lead to foreign object debris (FOD) destroying the ship while it is in operation. The other scary element is the apparent lack of work stands or platforms for the mechanics. When a plane gets built, it is important to build work stands or platforms first so that the mechanics have a place to stand wherever they need to be. As you can see from the pictures, they are doing their work standing on ladders. In addition to the inefficiency factor mentioned earlier, this also leads to ergonomic and safety issues. A mechanic standing on a ladder can't do the same quality job as when both feet are firmly on a platform, especially if any riveting is involved. Oddly, SpaceShipTwo has platforms for their mechanics but the MotherShip crew only has ladders. I was actually interested in taking a ride on this until I saw the pictures of their work areas!
If anyone from Scaled wants me to come out and do a full-scale industrial engineering evaluation, feel free to contact me by replying.

Another Take on the Box (Score:3, Interesting)
The writing appears to be dimensions, the boxes are used for ergonomic tests to make sure the various black boxes inside the vehicle can go in and out the doors. This is typical Rutan construction with rounded cutouts to avoid stress concentrations, that works well in carbon construction because theres not much ductility in the material. Mockup fit tests like these are typical and sometimes work better than trying to simulate it in CAD.
There's a QA label at the top, the QA department has measured and labelled the boxes.
Admittedly the box looks like it's being used as a weight at the time the picture was taken. But not for bonding, I seriously doubt any bonding is being done in the assembly jig, or at room temp. On a craft like this the bonding must be done in an oven or autoclave and the bond prep must be done in a clean room which as has been pointed out this facility isn't.
From the look of the structure I believe this may be a non-flying prototype, at least the fuse and wing pods. But for limited production vehicles like this and prototyping shops like Scaled things don't always look high-tech pretty so it my be flight hardware, R&D often looks like this.

The problem isn't altitude, it's speed. The SpaceShipTwo will peak at 2600mph, which is in the same ballpark as the SR-71 but only 1/6th the velocity required to reach any sort of orbit.
It's still a neat craft, but it would need to fifty times as powerful to become a true spacecraft, capable or doing more than popping above the "space barrier" for a few minutes.

I'm not saying you're wrong. I'm not familiar with the naval traditions of every country out there. But the US and UK, at least, (And those two have about the strongest naval triditions out there.) have no particular problem naming new ships after ones that sank.
After the first aircraft carrier iteration of the USS Yorktown (CV-5) sank after the battle of Midway, we named a new one after her just five carriers later (CV-10), and we have a guided missile cruiser in commission by the name right now. Also, the USS Indianapolis was sunk quite famously and horrifically. But we have a 688 class submarine with the name now.
Sometimes, the best way to honor a fallen vessel, is to continue its tradition.

It is kind of fun that it looks like they're building a spaceship in a big garage. Factories are not always what you think they will be. I used to work for a company that built mini-supercomputers. Our factory was surprisingly modest. I used to love that we would make the official stickers (you know, don't stick your fingers in here or you'll get electrocuted) with the laser printer and cut them out with scissors.

I've seen a lot of molded plastic manufacturing facilities (mostly spa manufacturers or boat manufactures. . . or custom car parts). They all look just like this because they all do the same thing. They build plugs, then molds, then finished pieces. I don't know why anyone would expect this factory to be clean. They are always grinding and cutting and spraying. It's just not a clean process.
The important thing is they clean each piece before each step. It doesn't matter if some dust gets into the finished product, because it will be encapsulated in resin. As long as it's not too much, it won't have an appreciable effect. I know it's nice to think that it can be perfect and dust free, but it's just not possible.
