A hypersonic "SpaceLiner" would whisk up to 50 passengers from Europe to Australia in 90 minutes. The futuristic vehicle would do so by riding a rocket into Earth's upper atmosphere, reaching 24 times the speed of sound before gliding in for a landing. Many challenges still remain, including finding the right shape for the vehicle, said Martin Sippel, project coordinator for SpaceLiner at the German Aerospace Center. But he suggested the project could make enough progress to begin attracting private funding in another 10 years and aim for full operations by 2050. The current concept includes a rocket booster stage for launch and a separate orbiter stage to carry passengers halfway around the world without ever making it to space. Flight times between the U.S. and Europe could fall to just over an hour if the SpaceLiner takes off — that is, if passengers don't mind paying the equivalent of space tourism prices around several hundred thousand dollars.

Wow, can you imagine riding this thing? I'll be an old, old lady (and unable to afford it anyway) but what a thrill to ride at 24 times the speed of sound.
I wonder....what effects might traveling at such speeds have on the human body? Does anyone know?
Anyway....the idea of this spaceliner just makes me grin.

I LOVED it! However..if that was a measly 2.5g with those rather dramatic effects? What WOULD 3 and more feel like to average people boarding off the street and without conditioning to expect and cope with it? It was just amazing what that lower number felt like now that I see what it was? (I'd forgotten the figure tho I believe it was posted on the warning signs at the ride too)

there is no effect on the human body of that speed. The space shuttle spends days at 23 times the speed of sound. And the ISS spends months at 37 times the SoS. And that is using the "standard atmosphere" value for Mach. At hypersonic cruise altitudes, the speed of sound is pretty much a meaningless concept, since sound needs a medium through which to travel, and at that altitude, there is no air to speak of. Air density at 100,000 feet is only about one-one hundredth of that at the surface. That's why you don't hear a sonic boom when the ISS passes overhead.

I think it's incredible to think our children may look back on our time and marvel at the idea we could actually spend a day or TWO between flights, airports and connections to pure frustrated madness in getting from one point on Earth to another.
I have a feeling, if we all find a way to get through the immediate troubled times, it'll come. The kids in the future truly will see this as their 'blue marble' and not something like a HUGE planet how we mentally see it. After all, New York to England was once considered many days journey on an Ocean Liner and that WAS 'fast' transport. It's just amazing how tech changes perceptions of everything, isn't it?

I'm betting at least a good hundred thousand bucks.
