That would be a 155 minute flight from Boston to Seoul! :mmm:

QuoteU.S. Military 'scramjet' breaks hypersonic speed record
By Scott Sutherland | Geekquinox – Sat, 4 May, 2013
The Boeing X-51A 'Waverider'The Boeing X-51A, an experimental 'scramjet' missile for the U.S. Military, broke hypersonic speed records this week as it flew at Mach 5.1 for three and a half minutes.
The X-51A is nicknamed The Waverider, due to riding the shockwave of compressed air that it creates as it flies. Its scramjet engine is similar to a jet engine, but it can work at much high altitudes and much faster speeds. Jet engines are limited by altitude and speed because the air gets too thin and it's moving too quickly to properly ignite it. However, the scramjet is able to both slow the air down and compress it, so that it can concentrate and ignite the oxygen in the air, but then still force the air out the back of the engine at hypersonic speeds.
The X-51A test took place on May 1, when the Waverider took just over six minutes to fly 230 nautical miles (425 kilometres), reaching speeds of over five times the speed of sound.
Although this test was conducted by the Military, it apparently wasn't to test for a new weapon, but as a general test of the technology for future applications.
"This demonstration of a practical hypersonic scramjet engine is a historic achievement that has been years in the making," said Darryl Davis, president of Boeing Phantom Works, according to Reuters. "This test proves the technology has matured to the point that it opens the door to practical applications, such as advanced defense systems and more cost-effective access to space."
The staff at Boeing are looking into its potential for commercial air travel, calling it the 'warp speed of today'.
The first test of the Waverider, back in May 2010, saw the vehicle reaching a speed of Mach 5.0 for 143 seconds. The two tests after that were less successful, with the test last August ending in failure, apparently due to a fault in one of its control fins. However, this week's test was seen as a complete success.
"It was a full mission success," said Charlie Brink, the U.S. Air Force's X-51A Program Manager. "All we have learned from the X-51A Waverider will serve as the bedrock for future hypersonics research and ultimately the practical application of hypersonic flight."

That's a lot of rape.
Why would this ever be used commercially?

If it's possible, why not?
The real question is how much fuel was consumed, and the engine efficiency.
No the real question is: Who fucking cares?

Because it's not economically viable. And even for the military, it doesn't really serve much purpose. The days where we needed jet fighters to go really fast are long behind us.
Yeah, we've circled back around to biplanes.

For wealthy businessmen.
For you and me it would still be 12 hours squeezed into a tiny seat on a regular plane :(
:yes: Your time is not valuable. :)

No. Telecommunications has made it ridiculous to spend that kind of money.
'cos there has been SO much interest in commercial supersonic aircraft since Concorde went boom. That's 40-year-old technology now.
Flying to New York in 3.5 hours is now consigned to the "will never do" pile, along with eating up the Post Office Tower revolving restaurant, curse you IRA!

Tim has always baffled me with the way he doesn't understand the economics of technology.

Not entirely. Hypersonic craft might be a tad hard to intercept and be able to carry out more missions in the same amount of time, allowing to cut down on procurement, maintenance and training. In addition, they could end the need to maintain expensive, vulnerable and politically inconvenient bases all over the world.
Nobody really intercepts anymore. And you will run into fuel issues if you try and cut back on basing.

We actually need A/C with a long loiter time and some ordinance... oh yeah, we have 'em... Predators.
I'm hearing that transports have become cool again with the pilot-wannabes because they see the writing on the wall. The days of fighter jocks are numbered.

Not really. Gonna be tough to fly those drones remotely when the Chinese blasts the C3 network to cyber-smithereens and the monitor goes blank when the uplink is dead.
You'll still need human pilots on station.
That would be the USN pilots flying off the carriers. :mad:
The USAF Academy is noticing more pilots opting for transports, as the guys who really, really want to fly stuff in person knows that's where it's at. The guys who just wanna blow shit up are going into preds and not into the fighters, etc.
Besides, the whole USAF will lose their shit and surrender when the Chinese take down their email.

Or, more likely, they will demand (and get) more funding for STRATCOM. And demand that a USAF General command CYBERCOM.
And then they will rip up the old carpet and put new, blue carpet in. And then they will get into pillow fights and have the clowns come out and tickle them, just like boot camp. And then they will bitch about being picked on by the other branches.
Plus ca change...
I didn't get any clown tickles. :mad:

Great answer. :hug:
Except right now, my skills are wasting away as I perform an under-appreciated (but important) admin-hell job. :(
What's a "rope?" :)

Some kid in technical training school who thinks he is better/more special than his peers, and is hoping to suck off some glory/power-trips from the people in charge...but who usually actually treat him like crap, or is forced to baby-sit the slackers and misfits.
Thanks. Any idea why they're called ropes?

Good. We need to muscle up the air train.
