Mach 6 Test Aircraft Set For Trials 131
coondoggie writes "The aspiration that jets may someday fly at over six times the speed of sound took a very real step toward reality recently, as the US Air Force said it successfully married the test aircraft, known as the X-51A WaveRider, to a B-52 in preparation for a Dec. 2 flight test. The X-51A flight tests are intended to demonstrate that the engines can achieve their desired speed without disintegrating. While the X-51 looks like a large rocket now, its applications could change the way aircraft or spaceships are designed, fly into space, support reconnaissance missions and handle long-distance flight operations. At the heart of the test is the aircraft's air-breathing hypersonic scramjet system."

Engines reaching desired speed without disintegrating....thats a GOOD feature to have.

Depends almost entirely on how fast you can get on scramjets. I don't think Mach six is enough to make it worth the bother. But I'm pretty sure Mach twelve would be enough to make it worthwhile.

This is actually a bigger step towards making a mach 6 missile [popularmechanics.com] rather then a mach 6 plane....

And on that issue - the market has spoken loudly and clearly. "It ain't worth it".
Yeah, I know the Concorde made a paper 'profit' towards the end - but the proof is in the amount of money the airlines were willing to spend to keep this 'profitable' airliner in operation, which coincidentally is equal to the number of Concorde's still in service...
Zero.
I you can't make enough money to pay your own maintenance bills, then making a 'profit' is pretty much meaningless.

Hmmm...I'm reading my post, and I don't mean to say that it would be great 9/11 would still happen. Don't get me wrong - 9/11 sucked and I would never want that to happen again. But, when I say "what's great" is the fact that nobody seemed to stop and think about how pointless many/most of the security measures actually are. (AKA, I was attempting sarcasm and it definitely did not come through...my apologies.)

You sound very sure. I'm curious, how would a Patriot (traveling at its top speed of Mach 5) overtake and intercept something traveling at the same (or greater) speed given that the latter has a rage of 600 nautical miles and the former has a range of 99 miles?
Are you sure that stealth is a priority given the X-51's intended mission [popularmechanics.com]?

Scramjets would be nice for a high speed reconaissance platform or bomber though.
