Boeing 777 Crashes At San Francisco Airport 506
Asiana Flight 214 from Seoul crashed while landing at San Francisco Airport today. Early reports suggest the plane was unstable as it touched down, which led to the tail of the plane breaking off. There are no official casualty reports yet, but passengers were seen walking off the plane. Preliminary estimates say one or two dead and 75 being transported to area hospitals. (Others are reporting two dead and several dozen injured.) Eyewitness report: "You heard a pop and you immediately saw a large, brief fireball that came out from underneath the aircraft," Anthony Castorani said on CNN. "At that moment, you could see that that aircraft was again starting to lift and it began to cartwheel [Ed: he likely means spinning horizontally, like a top]. The wing broke off on the left hand side. You could see the tail immediately fly off of the aircraft. As the aircraft cartwheeled, it then landed down and the other wing had broken." The media has estimated about 290 people were on board the plane. The top of the cabin was aflame at one point, but it's not known yet whether that affected the passengers. "Federal sources told NBC News that there was no indication of terrorism." Some images from the news make it look like the plane may have tried to touch down too early, hitting the seawall just before the runway.

For example, AF447 was not directly caused by any hardware failing - it was due to the pilots not following procedures and good practice.
If you read the black box transcript from AF447 the most notable single problem was that two of the three qualified pilots in the cockpit believed that the stick was being pushed forward, when in fact it was being pulled back.
When a plane stalls, a common panicked reaction is to pull back on the stick in an attempt to point the plane back into the sky. A lot of training goes into eliminating this instinct, because the solution is actually the opposite - point the noise toward the ground to regain speed. IIRC, the copilot was pulling back on the stick for the last several minutes even as the pilot and the alternate pilot (or a flight engineer or something, I forget) were saying things like, "we're pushing on the stick, why aren't we gaining airspeed?"
The communication problem was largely caused by an major Airbus design flaw: the sticks between the left and right seats aren't linked. In other planes, the pilot would have known the copilot had the stick pulled back because the action would make his own stick move back as well. On AF447, the pilot saw nothing other than the copilot's hand on the stick and assumed he was doing the right thing, and in the understandable confusion as they struggled to gain control of the plane the copilot never verbally corrected the misconception.
Certainly pilot error in response to some external factors that aren't that uncommon (like a pitot tube freezing) was the direct cause of the crash of AF447, but a more sensible flight control design would have likely prevented the pilot error.

Incorrect, there is no design flaw. As designed, if both pilots make a flight control input simultaneously, they will receive an aural warning: "Dual Input". They will know about it and either pilot can take priority over the other by pushing a button on the stick which will lock out the other.

When the pilot then gave the plane the correct input (nose down), the plane picked up speed and the stall warnings began again. Completely the opposite of what's actually going on, and probably confused the hell out of the pilots. At that point they probably guessed they were experiencing an electronic/computer problem, and probably began disregarding all the alarms they were hearing.
It's tempting to blame the accident on how easy it is to miss the "dual input" warning during a confusing and dangerous situation where all sorts of warnings are going off, and say that a force-feedback system like Boeing uses is superior. But with Boeing's system, one pilot slumped over or deliberately pushing his control column to crash the plane would hinder the other pilot from controlling the aircraft, possibly causing an accident [wikipedia.org]. With Airbus' system, the conscious pilot just pushes a button and he has complete control. It's not that one method is better than the others, they're just different, and vulnerable to different failure modes. AF447 just happened to hit upon a failure mode of the Airbus system.
It's also worth pointing out that the other two major crashes caused by disorientation following instrument failure were 757s. So while the dual inputs probably added to the confusion, it's still highly likely AF447 would have crashed anyway even without the dual input problem. The overwhelming cause of the accident was spatial disorientation coupled with reluctance to believe the instruments after a systemic failure (the airspeed inputs feed into multiple other systems that update the pilots on the state of the plane).

It also turns out that an aircraft in flight is one of the most predictable engineering systems - it's a single self-contained structure where there are only two unknowns: weather and human factors. Outside of those, manufacturers develop good working models of their systems and then test them extensively until they find failure points. Considering the uncertain factors, weather was a major cause of accidents early in aviation before weather radar was a standard safety feature, and aviation forecasts were fine-tuned. Now that weather is largely an avoidable risk factor (excepting extremes such as flying into thunderstorms or freak clear air turbulence cells), it should hardly be surprising that the leading cause of accident is the one thing that is most difficult to design around. If you can find a way to make any complex system (aircraft, car, nuclear reactor, etc) idiot-proof without taking away control from the idiot then I have a prize for you.
But this is a conspiracy theory, so let's see if we can falsify it by testing specific consequences we might expect, if it were true. We would predict that there should not be events admitted to design fault that could not be pilot rectified, because then the manufacturers would be liable - the FAA/EASA/CASA/etc should bury any such case. These regulators would never stop aircraft from flying, since obviously no fault could be admitted to. Rather, a quick search shows a long history of documented design flaws: de Haviland Comet square windows, DC-10 cargo door, 787 battery fires, 747 cargo door electrical fault (AL182, PA103, UAL811, TWA800), 747 aft galley electrical bus being under refridgerator drip pan (QF2), many many engine failures (Delta 1288, QF32, CA786 to name a few). Not all of these flaws were fatal, but they are officially acknowledged as design and manufacturing flaws nonetheless. If the conspiracy were real, they should never have been owned up to. Instead, we see well-documented explanations of what the flaws are, and FAA directives on how they must be fixed. In fact, there have been many cases where the FAA has forbidden whole classes of aircraft from flying until design flaws are rectified - most recently with the 787 battery problem.
When you consider that there are 10s of thousands of aircraft in the air at any one time and the failure rate is so low, it's obviously that engineers have gone to great lengths to make the design-build-maintenance-operation process for modern aircraft very reliable. Obligatory car analogy: ask yourself how often cars crash because the driver messes up, and how often cars crash because of a design flaw. Again, you'll find human error completely dominates.
Like most conspiracy theories, a little research and a bit of common sense goes a long way to shooting down bogus claims.

The term "cartwheel" has different meanings to different people. Unfortunately, just like with the Boston Bombing, CNN rushed a story out without getting its facts straight, though at least this time it was somewhat more substantial than pure speculation.
At this time, it appears the plane's air speed was too low on final approach, and the pilot may have over-corrected by throttling up and then (mistakenly) putting the nose further up as a panic measure; This resulted in a severe tail strike on the sea wall, and the plane would have become aerodynamically unstable immediately after.
Typically in these scenarios, the plane (appears) to shoot upwards briefly due to the sudden change in weight distribution, and comes down on angled heavily to one side (having lost any ability to control lateral movement). The wing will typically sheer off, as they're actually designed to break away from the fuselage in such an event, and the plane will roll onto its roof then (if speed is high enough) or the nose will take a digger, break off, and the whole thing will flip in the air and then promptly "face plant" in the dirt in one piece.
Either way, the plane did exactly what it was designed to do -- separate the flammables from the fuselage where the passengers were, and maintain integrity until all motion stops. The emergency crew's prompt response is what saved everyone's lives -- most people don't die due to the impact or fire, but rather smoke inhalation.
This is a text-book crash landing, and the investigation will now focus on whether a mechanical fault caused the plane to lose speed at the last moment (bird strike on engine is common), or whether the pilot neglected to flare correctly. Judging by the debris, it looks like it would have been a steep descent with flare at the end -- which results in a faster landing and is preferred at high-volume airports, over a shallower approach, with less flare. If the pilot is inexperienced, distracted, or any number of a dozen other things go wrong (one plane crash I know of was due to a circuit breaker trip-out which meant the captain did not have 'stick shake' or stall alarm warnings in this exact scenario) -- there's very little time to react, and even going to full power take off speed will not prevent disaster due to the steep descent angle, lack of altitude, and lack of speed.
Any airplane pilot knows the key to a successful crash landing is speed and altitude -- they add precious seconds to react to an emergency. This plane had neither.
Re:No Cartwheeling (Score:5, Informative)
There are actually bits of debris on the runway [turner.com] starting almost with the rocks separating the runway from the bay. The integrity of the fuselage says it did not cartwheel (objects this big don't move in one piece like the movies - they'll disintegrate with just moderate lateral forces). But the debris trail and missing tail suggest it came down at a high angle of attack hitting tail-first possibly from a stall (in a regular landing you hit landing gear-first), then hit the ground hard enough to collapse its landing gear and skid off the runway. The jagged yellow partial dome you see at the tail end of the fuselage is the plane's aft pressure bulkhead - the end of the pressurized section of the fuselage. So nobody was in the tail portion which broke off.
The high AOA suggests the pilot was pulling up trying to gain altitude (or at least decrease the rate he was losing it). Possible reasons are an engine problem (with inadequate thrust, pilot was trying desperately to glide a little further to make the runway) or some failure of the flaps (if they retract, they increase the plane's stall speed possibly causing the plane to drop out of the air). Or wind shear (sudden tailwind deprives the plane of lift and pilot pulls up to try to maintain altitude - unlikely given the weather). Or pilot error (was coming in too high and tried to bleed altitude too quickly, instead of declaring a missed approach and trying again), though the tail striking short of the runway makes this unlikely unless the pilot accidentally put the plane into a stall.

That's what I would have thought, but it turns out someone had a camera pointed in that direction at the time of the crash, and even if it wasn't strictly a cartwheel, it is completely reasonable for a witness to describe it that way as it does look like it spun on at least a 45 degree angle. Could just be the angle the camera though (An animated version of the events shows no such thing).
It's also possible that the footage is from a completely different crash. Wouldn't be the first time.

There is no general requirement or expectation that airports visually record all runway events.

One SFO runway is 2.25 miles long and there are 4 independent runways. I'm guessing you would need at least 32 costly all-weather cameras lining the runways to have a chance at capturing most, but still not all, runway activity, and this is not done; airports have better things to spend those tens of millions on.

It is justified. If only because the underlying tech that brought so many images of the crash so fast from smart phones and whatnot give evidence of the degree that new tech is influencing news.
Also of techie interest is that so many of the passengers survived such a destructive crash. Planes today are a lot more crashworthy than the last generation.

This doesn't really sound like geek news.
One rumor I heard was that ILS (or some portion of it) wasn't functioning on the runway the plane was landing on (28L) so the pilot was making a manual approach without the automated glidepath alerts he'd normally have. If this is true, then this gives the story a technology/geek tie-in, and touches on issues like whether or not humans (pilots in particular) have become too reliant on machines and when the machines fail, humans don't have enough experience without them to be an adequate back up.
Though I haven't seen the ILS issue reported in any official reports, so maybe it's not true.

I'll be willing to bet that in fact this is another incidence of uncommanded engine rollback, as caused the heathrow crash just short of the runway. Unfortnately, I have no buttcoins to bet with you though.

The vast majority of landings is not automated - they are flown manually so that pilots have some experience actually flying aircraft instead of pressing buttons and turning knobs.
Re: (Score:2)
The pilots have to manually land most long-haul flights or they won't do enough landings to remain certified. I think a lot more short-haul flights are automated.

The pilot HAD to manual land, the ILS system and PAPI glidepath height assistance for runway 28L (and 28R) at SFO is down, as reported in the current NOTAMs [faa.gov](Check for SFO)
That means he was relying on nav beacons and glidepath estimates to come in. Given that SFO's beacons are approx 1.2 miles apart, if he picked the wrong beacon to guild his descent he would have been too high, dropped steeper than usual to get down once he noticed the discrepancy, and didn't have the necessary power to flare and ascend at the end of the runway, so he tailstruck. That makes it pilot error, but confounded and mitigated by most (if not all) the regular guidance and assistance systems they rely on being out of commission.

Except that right now, there's little to no ILS at SFO, as a result of government-mandated construction work to shift the landing zone inland (ironically, to prevent this exact situation), requiring the antennas to be relocated.

Well, that's your problem, then, since autoland has been around for a while and I have been through a zero visibility autoland landing all the way down to the runway. On exiting the plane, I've asked the first officer if they did it manually or using autoland, she said autoland. It was a by-the-book landing, by the way, as far as I could tell. Very smooth.I could tell it was a bit of a crab landing since the nose swayed right as soon as the main gear touched down. So, it was autoland with side wind, too.

It is not used during take off or landing, and although either could be handled by computer, I'm not aware of any passenger aircraft that has such a fly by wire system. All of them are on the drawing board.
Autoland systems were developed in the 40s and perfected in the 60s by the Brits.
Developed for military purposes and then perfected for commercial purposes because England had endless problems with zero visibility due to their fog + pollution.
Autoland systems are so accurate that a fudge factor was added in, since multiple aircraft will all land on the exact same patch of runway and destroy the surface.
I can't say why you're "not aware of any passenger aircraft that has such a fly by wire system."

The formally correct term is "groundloop", although "violent yaw" would be valid too. A spin in an airplane is quite something else, and it doesn't happen on the ground.
