The new speed record for a jet-powered aircraft, set by the US space agency (Nasa) in November, has been recognised by the Guinness World Records. See article here. (http://news.bbc.co.uk/2/hi/science/nature/4115156.stm)

Wow I'm living in SCi Fi world. Could someone invent a time machine to take me back to when things were a bit simpler!
:lol

Hehe... nearly Mach 10 is pretty impressive and blows away the former record holder the SR-71!

its not that bad. iirc, a scramjet is just a tube with fuel injectors, less complicated than props or jets.

inside the tube, they inject fuel and light it, that all there is to it. only problem is that it needs to be moving to work, so that nasa thing needed to be dragged up to mach 9 to start!

damn that is fast !

As more and more science fiction becomes science fact.
How long before we attain warp speed? LOL

I'm a bit disappointed because such records are usually tied to conditions such as actually landing or otherwise recovering the vehicle for post-flight inspection.

Maybe, but the SR-71 took off and landed under its own power.

Next up, Guinness awards NASA the record for "highest functioning nuclear reactor" for the power supplies onboard the voyager spacecraft.

Ahh a bit more complicated in reality, the idea is basic as you say in a Ramjet (Bomarc Missle) or a Pulsejet (German V-1).

"Scramjet is an acronym for Supersonic Combustion Ramjet. The scramjet differs from the ramjet in that combustion takes place at supersonic air velocities through the engine. It is mechanically simple, but vastly more complex aerodynamically than a jet engine. Hydrogen is normally the fuel used."

I dont think we will be riding on any very soon.

Well I would think that actually landing and/or otherwise being able to recover the vehicle would be needed to call any such run successful.
Lawndarting it would kinda take away some of the joy of breaking such a record not to mention ruin your day overall dontchathink? LOL

Of course I prefer the SR-71, it was such an awesome plane! I saw it every year between 1982-1991 and even saw one depart the country with a pair of T-38s! :)

"The goal of the Hyper-X program is to flight validate key propulsion and related technologies for air-breathing hypersonic aircraft. "
all they are doing is testing the engines.

eeeek... welll dont know like you but i dont wanna travell mach 9... coz i have the only one stomach.
Anyway it seems to fly also pretty high.
-
It's okay Lada, it was unmanned anyway... but maybe in the future you'll get your chance of Mach 9!
BTW I went to Plzen a few weeks ago! Interesting place, especially the beer.... $0.80c (53 pence) for 0.5 litre (nearly a pint)!!! WOW! hic...hic...

this must be perked !!!!!!!!!!!!!!!!!!:lol

When a brit comes in and talks about pints of beer, he don't mean the amurrican pint, but the Imperial Pint (http://en.wikipedia.org/wiki/Imperial_pint).

The 0.5l I saw were going for 24 Korun Ceskych. I had a couple Budweiser Schwarzbier vom fass. A very lovely drink indeed! It was kind of cross between an ale and a stout! Thankfully nothing like the US Budweiser (since Budweiser is actually Czech!). I also had a couple Pilsner Urquell since I was in, er, Pilsen! :)
Both places were nice restaurant/bars so I dare say that you could get stuff much cheaper! I couldn't remember how much spirits and cocktails were going for, apart from it being incredibly cheap, something like $1 - $1.50?
Hoping to go to Prague before the end of the year too!
