SourceWASHINGTON – The Pentagon has finally released a report about what went wrong when its Hypersonic Technology Vehicle (HTV-2) failed just minutes into a test flight last year and barreled into the Pacific Ocean.
The unmanned, arrowhead-shaped aircraft, which one day could allow the US to strike anywhere across the globe in less than 60 minutes, was strapped to a rocket and launched from California's Vandenberg Air Force Base last August.
The drone coasted at speeds of 13,000mph (21,000kmph) -- 20 times the speed of sound -- through the Earth's atmosphere for less than three minutes before ultimately failing and switching into abort-mode just nine minutes into the flight. It splashed down short of its intended target near the Kwajalein Atoll in the Pacific.
Defense Advanced Research Projects Agency (DARPA) said an analysis of the crash showed that high speeds peeled off larger-than-expected portions of the vehicle's skin.
Officials anticipated some of the outer shell would gradually wear away, but rapidly-forming gaps on the skin created strong shock waves around the HTV-2 and caused it to roll abruptly, the report said.
Military researchers, however, were hopeful that they could learn from the mistakes of the failed flight, especially after the first HTV-2 mission in April 2010 -- which also terminated early -- prompted successful adjustments to the craft's aerodynamic design.
"HTV-2's first flight test corrected our models regarding aerodynamic design within this flight regime," Air Force Maj. Chris Schulz, DARPA program manager, said in a statement. "We applied that data in flight test two, which ultimately led to stable aerodynamically controlled flight."
Schulz added that data collected during the second test flight "revealed new knowledge about thermal-protective material properties and uncertainties" for flights at such a high speed in our atmosphere. Going forward, that data will be used to modify how the vehicle's outer shell responds to heat stress, DARPA said.

It doesnt matter about humanity now..
This thread talks about technological innovations...
We mustt admire the technology created by them, whateva purposes they use, which can be very bad as well.....

Maybe it was because it was using fake chinese electronics.

As far as tech & innovations are concerned the US is still way ahead of any other nation in the world, remember the internet that we're using today was DARPA's pet project some ~40 yrs back !

For us the Muslims its the same as appreciating how technically advanced is the gun pointed at our heads....
Eventually all of their weapons are being and will be used at us...
Now you will start who is responsible debate? and i will Quote a good old story..
A lamb was quenching its thirst
In the water of a pure stream.
A fasting wolf came by, looking for something;
He was attracted by hunger to this place.
What makes you so bold as to meddle with my drinking?
Said this animal, very angry.
You will be punished for your boldness.
Sir, answered the lamb, let Your Majesty
Not put himself into a rage;
But rather, let him consider
That I am taking a drink of water
In the stream
More than twenty steps below him;
And that, consequently, in no way,
Am I troubling his supply.
You do trouble it, answered the cruel beast.
And I know you said bad things of me last year.
How could I do that when I wasn't born,
Answered the lamb; I am still at my mother's breast.
If it wasn't you, then it was your brother.
I haven't a brother.It was then someone close to you;
For you have no sympathy for me,
You, your shepherds and your dogs.
I have been told of this.I have to make things even.
Saying this, into the woods
The wolf carries the lamb, and then eats him
Without any other why or wherefore.

Petty jealousy. If a muslim country did this, everyone would be all over boasting about Islamic intellectual prowess in the service of Islam.Let the rants begin

India does not have any great manufacturing base .....accepted! But US in no way have any obligation to use Chinese electronics.

It was not mentioned anywhere, that it was going to be used against muslims...
And Pls dont generalise muslims as a whole, as there are many muslims countries...
U can talk about Muslims of ur country, and i about mine, but u r not representing the muslims as a whole...
And pakistan did celebrate its N weapon as ISLAMIC bomb....
However i acknowlwdge ur last post, which is true, it belongs to the defence forum...
And i don like bringing politics onto such threads...
