These photos shows no initial fire damage to the top of the fuselage. Fire probably spread to the cabin walls and ceiling after fire from the right engine penetrated the fuselage on the right side.




These photos shows how the fire likely originated in the area where the right engine lay beside the fuselage after it broke off the wing.

Today's airline training teaches pilots everything except HOW TO FLY THE
AIRPLANE.
Ain't that the truth, as there seems to be a complete lack of understanding when it comes to the stick and rudder principles. Not just reserved for airline training either, as the blind (who were not taught properly) are partially creating the next generation of the blind.
Time for some Organisations to stop enforcing the 60 or 65 age limit (on those who are still on top of their game, and whose expertise they sorely need) in an effort to maintain the competency, experience, and safe helmsmanship which their fare paying passengers are entitled to??
Regards to all the full bottles out there who have a proven record of doing it as it should be done.

We have first hand accounts of professional pilots stating what they observed when they worked at Asiana and in Korea. It is evident there is a widespread deficiency among Korean crews (definitely not the only ones who suffer from this) to conduct proper visual approaches and landings.

Now take that pre-existing factor and add it to what would be a perfectly standard approach on a CAVOK day for a competent crew, take away the ILS GS, the VGSI, and suddenly these guys are left clueless.

No doubt the final report will indicate a clear point at which any other competent crew would have initiated a go-around due to the stabilized approach criteria not being met.

Hopefully they will learn sooner than later.

Irrespective as to whether it contributed to this accident in any way, it's outrageous that an airport the size of KSFO has no electronic or visual G/S.

Temporary VASIS or PAPIS can't have been that expensive until R/W works were complete.
It is part and parcel of all professional airline pilot training that one must be able to safely conduct a variety of approaches, down to the applicable minimums. This includes not only the standard ILS approach, but LOC, RNAV, and visual approaches, amongst others, and depending on the Ops Specs of the particular airline, circling approaches as well. RNP is the latest iteration, our tool boxes are increasing exponentially every year.

These operations are rigorously tested in the simulator every six months, any pilot falling short of acceptable standards is sent for retraining, in the event said aviator still comes up short, s/he is immediately, and without remorse of any kind, shown to the nearest hole in the wall.

Most call it the door. It is pretty bleak on the other side.

No more of this nonsense please.

Heard that also from one of the pax on the news.
Just before impact engines spooling up.
CVR and FDR will tell all soon.

My Son-in-law is a CFI-MEI. He says his Asian students come over here for their specialized JAA/EASA and FAA ab initio training. He says while they're on their landing rollout, the tower might say "exit on taxiway Juliet," and the student will do everything to make that turn, even if it means collapsing the gear to make that exit, when "common sense" dictates a safer course of action would be to respond "unable" and take, say the next safest exit. These are the students who head back and are placed (from a Seminole) into a B-777 F/O position. Clueless! No common sense! Cannot make a decision outside the box! incredible. I've been flying in and out of SFO on a regular basis, and their 28's G/S's and PAPI's have been OTS for a while (don't know why?), but who cares when it's CAVOK? Just Programme your own glide path (VNAV, HGS, etc.) and keep a visual scan, inside, then outside, etc.

I don't care how many hours you have chalked up 'YOU WERE NOT THERE" !!!!to make such disparaging comments re the flight crew without any knowledge of what has just occurred is beyond me.Why not wait like everybody else to get the facts instead of being a bunch of smart arses prior to knowing the facts,just like you would wish if you had been involved in such an event.

Turns out that a friend of mine was on this flight. He is basically ok. Here's a Facebook post from his wife, who apparently changed her own flight to an earlier one:

Ben is alive @ sf general hospital. Thank u god from the bottom of my heart. My kids need their loving dad who i am so proud!!! Ben was sitting next to the exit door. Seat # 30K. opened the exit door and help 50+ ppl out wz broken ribs from the crash. He calmed ppl down n helped to get them out before too late. Ppl were injured, bleeding n screaming. Flight attendances were overwhelmed n Ben did best to help other passengers. He thought the plane was so low when he saw the water n runway was too closed and the pilot put the gas it was too late. Plz forward this posting to let the news channels. So they know what exactly happened. (I supposed to flight back with him in the same flight then changed to the earlier flight. From now on I will travel in different flights.)

To those of you saying the pilots would not be used to visual approaches how are you backing this up? I ask this with total amazement because isn't it a basic rule of flight to be able to fly visually? I know it is to me.

I would get on a flight to a destination if I knew G/S was out but I would not get on an A/C if I knew crew could not fly visual approach .

2 Fatalities were found "outside the plane" ...."on the runway".
How'd that happen ? Crew from aft galley ? (Aft pressure bulkhead busted out in pictures)

Big aeroplanes, legacy carriers and Asian airlines..the triage does nothing to encourage visually flown approaches. Infact, a visual approach is anathema to the firm I work for and on the 777 fleet, rarely flown either for real or in the sim..due "threat"..wtf!!! For the kids doing right seat conversions to type, an end of sim VMC, no vasi, no ILS approach, under..lets just have a go and no test threat...is a real eye opener!! Flying schools, or at least flying school precursors for the airlines do not engender a culture of visual and manual flying. Low energy conditions, stall incipients etc are all covered by modules and the insurance of protections by the myriad of auto systems. Mix that with the barrier culture of Asian "face" and the risk of incident is increased immeasurably. The CVR will be an interesting if not indicting piece of evidence in MHO....

Agreed.

It's worth noting that there are RNAV (GPS) approaches published for both 28L and 28R that have 200' AGL minima for aircraft with LPV capability.

I'm not familiar with the 777, but it perplexes me why the crew would not have elected to fly a coupled RNAV (GPS) approach if the ILS was NOTAMed off the air.

Mic Dundee,
It would seem your son in law is not doing a very good job of instructing if he sends these chaps home unable to "think out of the box" or show some airmanship . Perhaps they need to use another flight training school.

One might say the same about PPRuNe, no?

Those two sources seem to be doing a better job than many of the "official" sites and ALL of the media.
If I may, there is a definite veridicality between various data sources. PPRuNe makes no pretentions to be other than advertised. There is no "data" here. Flightaware provides "data" but does not indicate for the user anywhere what the data is based upon, and neither does AvHerald. I've seen time errors in Flightaware and wrong reporting in AvHerald. Doesn't mean they're to be dismissed, but it does mean that they must be taken with a grain of salt.

I do flight data analysis and know that images and videos created from "data" have both the power to easily convince a credulous and information-seeking audience but can also be significantly in error and can draw parties to incorrect conclusions. Now in the end it doesn't really matter because the NTSB Report will eventually be written. But in the early hours of such events I think it is wise to greet all information as suspect because it is.

Those who fly the aircraft and who otherwise know this business first-hand generally speculate wisely but, as we see here, the thread is already more than a dozen pages of kapok, as is usual for industry events such as this. But that's okay too - it's "as advertised", but can't be taken as anything more than it is. Once in a while a gem shows up from someone who quietly knows his or her stuff but it takes an eye to avoid the general throng to capture the truth.

I happen to believe that this is nothing more than a visual approach gone wrong. I've done hundreds of them into SFO on various types, Quiet Bridge from the east, usually and it's a great amount of fun, generally but one must know more than just relying upon ILS. We'll see what the NTSB has to say.

From flying with them. Sad but true.

Aircarver - looking at the 777 floor plan, there are two crew seats with telephones aft of row 67 but in front of the galley. I presume the violently detatched tail section included these two seats and hence the crewmembers. The Cog aft limit will be calculated during the investigation- this is another variable along with sink rate/ AoA, SA of loss of stable approach , training/recency/CRM "culture", lack of standard vertical guidance cues, fatigue, and all the other possible factors raised above.

Here is the current RNAV (GPS) for 28L.

I`m wondering , what part of an EGPWS Warning WHOOP WHOOP PULL UP ! wouldn`t they have heard or understood with such reported sink rates below 1000`? Must have been lots of bells and whistles going off for the CVR Analysts to sink their teeth into.
At worst I would expect a "SINK RATE"...I wouldn't expect it to be going too bananas....
