Nebakenezzer posted:The ask the Pilot guy at Salon has a pretty good write-up of everything that went wrong with the Quantas A380: And while that's a whole load of bad poo poo happening, what gets glossed over is how much went right. One catastrophic engine failure causing a cascade of worse and worse problems, and yet the system worked. One weak link didn't break the entire chain, and aside from the groomers having to change a load of seat cushions and some inconvenience, everybody got home safe and alive not much more than a day or two late. When you consider how bad it could have been, it's a good thing the safety nets are there, and this incident highlights that they should never be lessened or removed in the name of cutting costs. As for repairing the plane for pride's sake, it's really out of Quantas' hands. Repairs like those required are well beyond the scope of an airline's maintenance organization. It'll be Airbus's own specialists and engineers who do this one, and if they can't do it, it can't be done. Beyond that, it'll be the underwriters who decide whether the it's even worth trying to repair. Quantas can probably still get out on loophole since I doubt they actually own the plane anyway, it's likely leased.

grover posted:The F-35B is, of the 3 variants, the one where there is really NO alternative at all but to fix it. 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. Fatigue cracks aren't always as easy as 'just add more metal' because load will usually take a single path unless it has reason to evenly distribute through others, which is difficult since metal isn't very elastic and so they have to both contain similar overall stiffnesses. More often than not, fatigue failures require a fundamental change to the design i.e.: reduction of sharp radii/corners or reconstruction of the load path so that spot stresses are reduced. Fatigue failure is also very hard to predict because by virtue of it being initiated by highly stressed regions, the material in said regions behaves in a very plastic manner (as opposed to elastic) and so crazy non-linear effects come in to play. It may be quite easy to patch this up, but especially with carefully designed, light things such as airframes, it's always possible that it is in fact very hard to solve too. Also, a lack of a fatigue limit is a bitch to deal with, for example when working with aluminium.

You can see and hear them take off regularly. The flash video doesn't show everything. When the missile is fired at 4:08, you can't really see it go off course due to the flares.

^^^That's exactly the video I had in mind, actually. One of my best memories from being stationed at Tyndall was sitting at the red light at the main gate from the non-flightline side of the base (a major highway splits the base into two sections) a few weeks after I got to the base. I saw an F-4 dressed in old-school camo take off...followed by a 4-ship of F-15Cs...followed by a 2-ship of F-22s. All in the duration of a single red light. I was rock hard for hours. Revolvyerom posted:Would it be cheaper to develop an entire line of aircraft to fit a niche role? That's a huge reason right there. More likely is that the airplane was designed to fit other roles slightly better, as it's expected to be required to fill them more heavily, but can be somewhat adapted to fit another role if need be, for less than the cost of an airplane that might do it better, but needs to be developed. I don't think the Marines need a 5th generation VTOL fighter to replace the Harrier. So yeah, I actually do think they could've done better than drive the cost of the F-35 into Raptor territory.

Having an aircraft with a decent air-to-air capability gives them a lot more autonomy so they don't have to rely heavily on the Navy or Air Force for air superiority. I think they can justify it, but it shouldn't be their primary goal. Now I'm curious if the Marines actually wanted in on the F-35 program and wanted to stay in it as the program spun out of control, or if they were politically driven into it.

The trend now with a lot of the higher ups in the Air Force and defense community is smaller, slower and cheaper. There's several proposals out there to take a plane like the Texan II http://en.wikipedia.org/wiki/Beechcraft_T-6_Texan_II and instead of just using it as a trainer, 'put a kit on that bitch' and use them for CAS and CAD roles. I know other countries are doing it, and it's about time we did the same. We can't afford to have F-22's and F-35's zooming around at plaid speed while the guys on the ground have nothing for Close air support. Fun fact I can't prove about the Texan II: The ejection seats make up half the planes total cost.

That's why they're considering smaller, slower, and cheaper DRONES. The utility of an orbiting Hellfire platform that's a laser-designator away from destroying the poo poo out of anything you want is far, far higher than anything else in a CAS role, especially given that there is no pilot to put in harm's way and no worry about how hazardous the airspace is. F-22s + Predator-style drones = the future Air Force.

Its very easy to oversubscribe your pilots/shooters. Now there is some more thought going into *what* gets to the operators. Atleast from what I've seen. I think they're making lots of mistakes. Stealth is passive tech. Jets need only minimal electronics to keep users from doing stupid poo poo and making them flame out. It takes less horsepower than is available in a micro controller to keep an inherently unstable aircraft pointed forward. And yet, somehow, we're running around with the equivalent of a cray supercomputer in these things? IIRC, there's two of them, for redundancy. We're to the point where the price for aircraft and maintenance means we need to maintain very, very small stocks of them. That single F22 going down took out what, 0.8% of the entire inventory? I can think of half a dozen ways of defeating such a small force of aircraft. What immediately comes to mind is very large bags of gravel... Or any opposing force with numbers 4x greater than the attacking sortie. Unless we're talking naval vessels, taking out a single anything shouldn't make that sort of change to the inventory. The design groups, and number of roles we want a single aircraft to fulfill is downright stupid at this point. Multi-role never beats specialist. I am not "all for" drones. I think if there's a place where they can have clear room to defend against anything, I think they've got a place. (I'm thinking fleet defense, and foreign airspace patrols in particular) Taking great care as to what information reaches your pilot matters. I think not nearly enough thought has been put into this. I think this is something that would easily be solved by a very small group of people, instead of the very large committee style planning that goes on now.

It really boils down to if you think the F-35B will be worthwhile or not. I see the thing like the space shuttle: too complex, built for too many jobs, and going to be stupidly expensive to maintain. Build a new VTOL airplane with modern, proven technology, and even if it costs a lot up front, having a reliable, easy to maintain plane will be worth it in the long run, both financially and militarily. It also confuses me why the Brits want carriers that don't have catapults on them. Carriers are expensive; you might as well go the whole hog.

Mahmoud Ahmadinejad posted:http://www.bbc.co.uk/news/business-11842597 Akbar Al-Baker has done this before. In fact, airline CEOs do this fairly often, and for one reason; they want to rework their deal. By bringing down some bad press, it will put pressure on the manufacturer to give them more of a discount. Qatar Airways has 30 787s on order, with options on 30 more, which in total would be worth something like $10 billion at list prices. That's a lot of change, especially for a product that will be at least three years late when all is said and done. And by calling out Bombardier, he's basically saying that he might be amenable to re-ordering the CSeries, if the terms are favorable to the airline. That said, there seem to be more questions than answers regarding the performance of the CSeries right now, especially with respect how much of its performance advantage is down to the engines, as opposed to the airframe. If most of the advantage is in the engines, Airbus and Boeing can simply re-engine the A320 and 737 and retain their dominance of that market. Airlines typically have quite a bit of power to negotiate and re-negotiate terms with an airframer, especially if their aircraft haven't entered the production pipeline, and they have been known to resort to some pretty shameful tactics to get their way.

Edit: they also still own and use a pair of Gloster Meteors (half the still-flying Meteors in the world -- there's one other in the UK and one in Australia) for testing ejection seats. I am far too amused by the fact that neither has a canopy over the rear seat (I mean, it makes sense not bothering to replace it after every test, but still). Click here for the full 800x508 image.
