Way worse a loss than the stealth helicopter thing? China might trade Iran a few thousand shoulder launches for it. Not good.

Those things need to have a self-destruct mechanism.

Instead of that I guess the thing doesn't crash, it just about lands itself when contact is lost.

Wot, six million bucks and it doesn't have an EPIRB?

Iranians showing off their trophy. It looked kind of cheesy at first and I wondered if it was a cobbled up fake. Guessing it was bent and they've fixed it up for display.

Can't wait to see them try to build their own version. :gomer:

Maybe we WANTED it to land intact so when the ChiComs or the Russkies copy it, all THEIRS will fail too!:gomer: All in all, we really have to be aware of the Death Ray that brought it down!:eek:

Yeah, looks like that starboard wing was cobbled together out of papier-mache' for the photo op.

This is why we can't have nice things.

Iranian electronic warfare specialists were able to cut off communications links of the American bat-wing RQ-170 Sentinel, says the engineer, who works for one of many Iranian military and civilian teams currently trying to unravel the drone’s stealth and intelligence secrets, and who could not be named for his safety.

Using knowledge gleaned from previous downed American drones and a technique proudly claimed by Iranian commanders in September, the Iranian specialists then reconfigured the drone's GPS coordinates to make it land in Iran at what the drone thought was its actual home base in Afghanistan.

I thought military gps was encrypted, how could they spoof an encrypted signal?

C'mon, it's Kashmar. We zip in, we pick it up, we zip right out again. We're not going to Tehran. It's Kashmar. It's like we're going into Utah.

Beer quality is probably about the same as Utah.

Our beer is quite good if you're smart enough know where to look.

Tried quite a few from Wasatch, mediocre at best, never tried Kensington. Should not have to "look" for beer. My state has a bar on every corner and too many microbreweries to count :D We enjoy an abundance of the three basic food groups: sausages, cheese and beer.

Wasatch is where you don't look. Kensington is the guy across the street who covers his house with hops vines.

U2 to replace Global Hawk drone for reconnaissance missions. Cheaper, more capable, more badass.

Pilot pressure suits.


According to the internet:
A pressure suit is needed as a redundant system. The hazardous physiological regime of high altitude flight dictates this. Also, since the cabin pressure of a U-2 is equivalent to an altitude of about 30,000 feet, the pilot must prebreathe 100% oxygen for 60 minutes prior to takeoff to avoid getting the bends. The pressure suit would be needed if the pilot were exposed to the atmosphere from a rapid decompression or having to eject from the aircraft. Two reasons for this are Boyle's law and Armstrong's line.

Boyle's law is that a given quantify of gas varies proportionately with the amount of pressure exerted upon it. We humans are used to 14.7 pounds of pressure per square inch (psi) at sea level. We are at the bottom of an ocean of air. This air has weight. The pounds psi at altitude is less than a half-pound. Armstrong's line says that at 63,000 feet pressure altitude, conventional liquids boil at 98 degrees Fahrenheit. If the pilot were exposed to the environment at 70,000 feet, the gases in his body would rapidly expand causing a disastrous burst. Not to mention what a "boiling" body temp of 98.6 would cause. Yes, it would ruin his whole day. Obviously this is not conducive to a successful mission.

How the hell does the engine function at 70,000 feet? Does it just lean out because 95% of the atmosphere is below the plane? Not much thrust would be required because drag would be very low. Neat clip, thanks.

I think the answer is that a jet engine is basically a compressor and at 500mph there's an awful lot of (albeit thin) atmosphere being stuffed into the engine.

I may need more alcohol to come up with a better answer than that.

Well there is an f'n rocket scientist on this board who could supply a long, techinical and possibly correct explaination :D

Just don't ask him about steel tube frames versus carbon fiber. BTDT.
