I haven't seen any other news reports, so until I do I'm not getting too excited yet. dietcokefiend posted:Serously...

It is designed to not be found. It'd be weird if it wasn't being tracked by home base since it was a training mission, but flying low and fast through mountains; who knows?

When they're flying CONUS, they've got their IFF transponder on. The FAA still owns all the airspace, even the military ranges. We have to make a few phone calls to reserve it for use, and even then Center can still take it back if they need it (this rarely happens, and it's always for a good reason). Anyway, if the Raptor is squawking, it's as good as a radar return as far as tracking goes. So as long as you've got line of sight and you're in range, you can see it...but if the terrain is mountainous there are a lot of factors that come into play-loss of radar/IFF contact, loss of radio contact, bizarro weather patterns, difficulty in detecting emergency beacons/wreckage, so on and so forth. Not a pretty situation at all. I'll be keeping an ear out over the next few days, I'm curious to hear how all this plays out.

New pictures of the Qantas A380 damage: http://www.theage.com.au/travel/travel-news/fuel-tank-puncture-qantas-a380-lucky-to-escape-catastrophe-say-reports-20101119-180bq.html quote:Confidential preliminary reports seen by Fairfax Media reveal that high-velocity parts spat from the engine tore through a fuel line and wiring looms, punctured structural spars in the wing, struck the fuselage between the two decks of windows, hit the fuselage belly and tore through wing panels. Talk about 100% luck that thing didn't turn into a giant flaming fireball.

Did not ignite and cause an explosion? The average punter will read that and assume like they always have that throwing a match in a container of fuel will result in a devastating explosion.

Ask away. I know a little bit (the QF-4s were controlled in the building next to mine at Tyndall AFB), but not a whole lot. Technically they are a UAV (the current term of choice is UAS-the S meaning System) if they're flown with the seat empty, but often there is a person on board even though they dont control it unless they have to.

I wouldn't want to be the engineer that signs off on a main spar repair in a hundreds of million dollar passenger aircraft. Whether or not they can replace a wing or part of a wing takes in way to many variables that only airbus knows. It totally depends on the design and construction. Not a modern airplane; but it's depot-level year long process to replace the center wing on a C-130 with a new sub assembly. I imagine that an a-380's wing would be "slightly" different than a herk which is pretty much an early cold-war flying tractor.

Kallikrates posted:I wouldn't want to be the engineer that signs off on a main spar repair in a hundreds of million dollar passenger aircraft. Qantas doesn't work that way. They've never lost an airframe since the jet age and they're not going to now. It'll be repaired. The 747 mentioned earlier that slid off the runway in Bangkok cost $250M+ to repair, and $200M to replace for a brand new one; they repaired it just to keep bragging rights. Like you say, the mainspar on those things is about the only bit that can't be fixed, so it'll probably be rebuilt from scratch but just enough left intact to keep the same manufacturers serial number. But it'll be "repaired" and the score card will show that Qantas has still never written off an airframe since the jet age

They are obviously flown via radio control, but is there an observing aircraft, is there a video camera going to a guy in a simulator setup? I assume that they are mostly flown in straight lines and not necessarily used for any kind of maneuvering during live fire...

Yea but technically speaking the aluminum is probably also dug up someplace else and shipped in too . If stuff is welded or put together in an odd one-time fashion it might not be possible. Who foots the bill on this if it turns out it was 100% RR's fault?

I would be very surprised if they couldn't replace the entire wing as a unit, but as to whether a sectional repair could be effected on the damage, it's probably more a question of confidence level rather than technical feasibility. quote:Who foots the bill on this if it turns out it was 100% RR's fault? Unless the root cause digs up someone having falsified test data etc, at which point it's time.

Boomerjinks posted:How about when they are used as target drones? They are obviously flown via radio control, but is there an observing aircraft, is there a video camera going to a guy in a simulator setup? I don't think a dedicated observer aircraft is launched, but usually when blue air (the good guys, now usually F-22s since the F-15s are gone from Tyndall) flies they're in a 2-ship or 4-ship formation. I actually don't know too much about the the QF-4 control setup. Based on some of the other equipment used regularly at Tyndall (ACMI) I expect they get a lot of telemetry data. The ACMI system can show raw data (like altitude, speed, angle of attack, bank angle, etc) or it can show you a 1993-ish 3d view realtime. I would expect something like that, but probably a bit more primitive (ACMI pods ain't cheap, and they certainly ain't disposable enough to be loaded onto a target). As far as maneuvering...if they're not turning, what's the point? There are a couple of reasons for the live-fire exercises. One is to validate weapons systems. Missiles and aircraft. Missiles have to be proven to work, and the best way to do it is to launch at a realistic target. Same thing for aircraft. You don't want the first realistic test to be in combat. The other reason is pretty much the same thing, except for pilots. It's one thing to fly a normal training sortie with no live weapons, make a "Fox-3" call on the radio and do some mental math to see if it "should" work as advertised, it's another to feel the aircraft shudder and watch the trail of smoke disappear in the distance, then see a fireball miles ahead. But that's not enough...you also want to be able to track your enemy through maneuvers, and put yourself in a firing position where he'll have a hell of a time getting out of a defensive position. So yeah, they maneuver, and if the blue pilot doesn't do his job right, he just might miss. It's happened plenty of times. There are some pretty awesome videos on youtube actually.

I'm sure the A380 wing (the skin) is made in one piece though (can't seem to find a YT of it but there was one posted on pprune) where the skin thickness varies enormously throughout the length. I imagine if they do decide to repair it will be very complex and extremely expensive.

In the whole scheme of things, reinforcing parts of the structure doesn't seem to be that big of a deal. There are always engineering changes/updates in projects this big. I think this may be part of the problem, strangely. I'm not sure when we started saying "we're going to replace our Xs with Ys, which is filled with all sorts of new technology we're in the middle of developing but we're still going to start using them four years hence", but it seems to me this causes problems.* It makes the developers focus on meeting an arbitrary deadline instead of getting all the bugs worked out. In the Osprey, for example, if they had just kept working on it, and had the marines just buy regular helicopter replacements in the near term, the Osprey would have had far fewer problems. It's the same process that creates bad software and video games. Also weird fact about the Harrier: it is the most deadly aircraft in the Western arsenal, having killed quite a few of it's own pilots over the years. Of course, the thing is basically just a giant turbofan with some wings and mounting points attached. *This is of course presuming defence contractors are not purposely proposing things that are insanely complex and over ambitious to begin with to keep the thing perpetually in development
