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.

*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

Defense contracts 101:
  • If you make your project go over budget and over schedule, you get rewarded with more money and time.
  • Contractors are frequently limited to what percentage of your project budget can go to direct (engineer/technician/people that actually do work) vs. indirect (management, facilities) costs; the obvious thing to do is to bill as much direct hours as possible so you can get as much indirect as possible.
  • Always bid on every project, even if you can't do it cheaper. If you win due to your history with the sponsoring organization, you can always subcontract out to one of the losers at the price they bid.

No, there should've been a purpose-built aircraft to fill that niche role, rather than force a square peg in there. The B is going to be the least-produced, but is responsible for most of the cost overruns and design delays. Force-feeding the Marines to buy off on an F-35 variant has driven up the cost for every other buyer, US and overseas, and all in the name of parts commonality...but by it's very nature, it can't take advantage of that "benefit."

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.

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.

And gosh durn it, nobody wants old airplanes.

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.


http://www.youtube.com/watch?v=xISpZYajveA

I always get a kick out of watching this clip (I have a .avi of it from a few years ago) as I grew up and still live in close proximity to their base airport (PDX). 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. I'll have to post the .avi if it's not too large. It's at home on my desktop and I'll be there later this week.

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.

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.

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.

This is the argument. 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.

Boeing Dreamliner 'a failure', says Qatar Airways boss

The chief executive of Qatar Airways has criticised Boeing over delays to the 787 Dreamliner, reportedly saying that it has "clearly failed". Akbar Al Baker said he had been "taken aback" by the problems that have plagued the delivery of the aircraft, the Reuters news agency reported.


Meanwhile, Boeing has announced it is revising its schedule after a fire on a test flight earlier this month. It had hoped to begin delivering the plane at the start of next year. Production of 787s is about three years behind schedule, with delays mainly a result of the supply and fitting of parts. A test flight had to be aborted on 9 November after a fire broke out on board. Boeing has blamed a piece of "foreign debris" in a power panel.

Qatar Airways has ordered a minimum of 30 Dreamliners, with the first due to be delivered in the last quarter of next year. Speaking at a news conference in Paris, Mr Al Baker said he had not expected such delays from Boeing, because the US-based company had "pride in its quality". "They have very clearly failed," he added. He added that Qatar Airways was considering buying more Airbus A380s on top of the five already ordered from Boeing's arch-rival.

Mr Al Baker was also critical of Bombardier of Canada, which has been trying to break Boeing's and Airbus' stranglehold of the airliner production business. He said Qatar Airways had been forced to cancel a planned order for the company's C-Series planes in July over concerns about their engines. "If they do not roll up their sleeves pretty fast then the [new Airbus A320] NEO will eclipse them," he warned.

Is this the first time that the head of an airline has come out attacking a manufacturer like this? I've never heard of it happening before.

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.

Yeah.

Will post the verdict when I get it. He should be in by now, it's past 10am there.

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).
