Klaus Schmidt writes "Virgin Galactic today unveiled their WhiteKnight Two mothership, called 'EVE.' It is designed to carry the smaller SpaceShip Two into space.
The rollout represents another major milestone in Virgin Galactic's quest to launch the world's first private, environmentally benign, space access system for people, payload and science.
Christened 'EVE' in honor of Richard Branson's mother — Sir Richard performed the official naming ceremony — WK2 is both visually remarkable and represents ground-breaking aerospace technology. It is the world's largest all carbon composite aircraft and many of its component parts have been built using composite materials for the very first time. At 140 ft, the wing span is the longest single carbon composite aviation component ever manufactured."

Probably the same stuff NASA does. I personally believe budgets *should* be kept small, even if artificially. This *forces* innovation. If they knew they had whatever amount of money they desired, I don't think the science would advance as far, or as fast.
In short, I think it's the lack of resources that forces people to come up with workable solutions to whatever problems they face with what resources they have at hand.

Where do you think the high costs of these things comes from? The design of a product for a given context is an expense that is, for mass-market products, paid for by the volume of sales. The market for space-shuttle seat-belts is probably 6 to 8 units, total.

I'm not saying space travel is easy, but in real life there's usually some reasonable compromise between "the most safety we can provide at any cost" and "the most safety we can provide at a reasonable cost, considering the inherent risk of this situation". But it doesn't surprise me that you've lost sight of that -- many people have these days.

Commercial airplanes aren't supposed to experience his acceleration (ie: why you need seatbelts) and when they do experience them people get injured. The space shuttle experiences decent acceleration quite often and it's one of the lower accelerating space vehicles. I'm sure fighter jets use quite expensive safety systems for that very reason.

The problem is, with tens of millions of dollars in the budget this project isn't lacking resources by any reasonable interpretation of the words. Further, comparing them with NASA is a bit misleading as the White Knight/SpaceShip Two craft operates in what is a fairly benign environment compared to what would be encountered by an orbital craft.

Mojave Air and Spaceport, California
Virgin Founder, Sir Richard Branson and SpaceShipOne designer, Burt Rutan, today pulled back the hangar doors on the new WhiteKnightTwo (WK2) carrier aircraft that will ferry SpaceShipTwo and thousands of private astronauts, science packages and payload on the first stage of the Virgin Galactic sub-orbital space experience.

http://www.virgingalactic.com/pressftp/content/Presspacks/VMS%20Eve%20rollout_thumb.jpg [virgingalactic.com]
Driven by a demanding performance specification set by Virgin Galactic, WK2 has a unique heavy lift, high altitude capability and an open architecture driven design which provides for maximum versatility in the weight, mass and volume of its payload potential. It has the power, strength and maneuverability to provide for pre space-flight, positive G force and zero G astronaut training as well as a lift capability which is over 30% greater than that represented by a fully crewed SpaceShipTwo. The vehicle has a maximum altitude over 50,000 ft and its U.S. coast-to-coast range will allow the spaceship to be ferried on long duration flights.
http://www.virgingalactic.com/pressftp/content/Presspacks/VMS%20Eve%20bow_thumb.jpg [virgingalactic.com]
An all carbon composite vehicle of this size represents a giant leap for a material technology that has already been identified as a key contributor to the increasingly urgent requirement by the commercial aviation sector for dramatically more fuel efficient aircraft. Powered by four Pratt and Whitney PW308A engines, which are amongst the most powerful, economic and efficient available, WK2 is a mold breaker in carbon efficiency and the epitome of 21st century aerospace design and technology.
The twin fuselage and central payload area configuration allow for easy access to WK2 and to the spaceship for passengers and crew; the design also aids operational efficiencies and turnaround times. WK2 will be able to support up to four daily space flights, is able to carry out both day and night time operations and is equipped with a package of highly advanced avionics.

Remember that commercial aviation in its infancy was also prohibitively expensive for the average consumer and many people initially bought tickets solely for the thrill of riding in an aircraft. These "thrill" flights would usually depart and land at the same airport, a thought that is somewhat puzzling to all of us who rely on its completely pedestrian, utilitarian use today. Cost, needless to say, bottomed out, especially after deregulation.
That said, the commercial uses of present-day aviation are obvious. Space travel, especially LEO, strikes me as something that still needs a killer niche to succeed over the long-haul. And remember Concorde, which for many reasons (not the least of which was the rather high-profile crash, and which was even more susceptible to the post-9/11 drop-off in commercial aviation use) ultimately collapsed.
Passenger aviation is notoriously boom-bust. Eastern Airlines, TWA, the list of companies with obviously sustainable business models that collapsed anyway is a mile long.
Who knows what commercial application someone with a launch system like VG's could come up with? I hope we have another Boeing in the works, but I agree that as things currently stand, it's got a much greater chance of becoming another Concorde.

In his novel Firestar [amazon.com] , the first volume of a future history attempting to be a realistic vision of the rise of human spaceflight, Michael Flynn had FedEx as one a major sponsor of private launches. Being able to deliver a package anywhere on Earth in 90 minutes, Flynn thought, would be an incredible advantage to a courier firm. With the rise of the Internet, however, there are ever fewer physical packages to be transported, and maybe no company would be willing to pay thousands extra for just a few hours less of delivery time. Now, except for space tourism, I'm hard-pressed to find any commercial use for mere orbital flights (as opposed to getting out there and mining).

That's seriously long-term. The only ways I can see space exploration resulting in less use of earth-based resources is if:
A. We develop a way to ship off significant amounts of people to colonies. Considering how fast humans reproduce, this is not likely any time soon at all. Colonies will not be a solution to population growth.
OR
