as long as they keep off the sound stage for this one.

Wussies!
Here's how real men go hypersonic!

<S> Great article funked! Never heard of that one before...

I also saw NASA's news and actually was taken aback. I didn't think they were far enough along to be conducting actuall test flight in less than a month.

NY to CA in 30 minutes!

You think congress would allow such a thing to fly overland? They could fly through the Antarctic. It would add another half an hour...

Even discounting the $30,000 ticket and 6G accelerations, that contraption is not very practical. Slow (turbo)prop-driven planes are the most energy-efficient means of air transportation

I can't see how it would be practical other than for very, very long distance journeys. The distance required to decellerate would surely be enormous.

It would be nice to cut down those 12 hour flights to Oz though.

Miko, if you leave the atmosphere the efficiency gets pretty high.

PS I'm glad you liked that article Beltfedd. That thing was designed in my hometown and I am proud of it.

The aim of scramjet technology is not for traveling across the world, but for leaving the atmosphere in a more efficient way. Space travel would become so easy if the technology becomes practical.

There's been some crazy stuff going on in the skies here in So Cal this past week. I've seen some massive contrails at stellar alts. Driving to work this morning the sky looked crazy. There was a a string of 5 contrails side by side. The center one was massive and about halfway into it it's splits off and turns into two contrails...one that makes a slow bank and seperates from the group...

I personally think the thing is already been tested and they're just holding that date for public viewing...

Lol, I was blown away by that article, I thought it was a joke/hoax for a second (I mean, they got their heat-resistant paint from a Hot Rod magazine! Heheheh). I had heard of ideas for nuclear-powered airborne aircraft carriers, but had no idea a nuclear scramjet had actually been built and tested! That would have been one MEAN MF if it had ever gone into use, scary to the nth power.

Didn't we also test fission-based rockets in the 60s? God, it feels so odd that here we are 40 years later, I look at this stuff and it seems like space tech (at least engines) was more advanced then...

Cold war did wonders I suppose, anyways, that's a subject for a different thread <S>.

Fission-powered rockets were very ineffective as I recall. They used nuclear explosions for thrust. No one has found a way to truly harness nuclear power for rockets that I know of. Ion engines though... those are pretty cool, only problem is that you couldn't get off the ground with one.

CA to NY in 30 minutes? What about the inboard meal and movie?

Damn, I can go to the west coast faster than Domino's can delivery.

I think there should be an age limit to board these flights, I got a really bad image of soft fleshy parts traveling 10x the speed of sound
