777 crashes at SFO

[95EagleAWD]

An Asiana Boeing 777 has crash landed at SFO

Early witnesses say tailstrike on landing... obviously a developing situation.

[lilmira]

Looks like some people walked away, hopefully they all did.

Another mayday episode?

[95EagleAWD]

Hearing that everybody survived. Great news!

[ZEDGE]

Some Samsung Exec was on board, says most everyone is fine.

Weather doesent appear to be a factor. Sounds a bit like BA flight that crashed that had issues with the Fuel/Oil heater.

However this Asiana used P&W engines, so thats likely not a factor either.

They're saying debris goes back to the seawall. I hate to say it but... nice day, visual approach; maybe the pilot just got it wrong.

Yahoo says one dead?

Yea thats a possibility too. Its unlikely that multiple systems in the flight deck functioned, however its also unlikely that multiple PILOTS malfunctioned as well (PNF still has a job to watch out for danger).

2 DEAD 61 INJURED and 60 unaccounted for (307 ob) - KTVU NEWS[1] - Sky News just reported 73-103 injuries; ~10 critical ////// NTSB conference gives impression that one of the deceased who was sat at the rear of the aircraft was ejected onto the grass

SFO shut down.
Watching the live helicopter footage right now the tail section separated at the rear pressure bulkhead. [the big green thing]
The tail is BEFORE the runway threshold (on the Chevrons even before the piano keys) on 28L. Landing gear separation from aircraft.
Looks to be a crack across the fuselage before door 4L/R; Typical shear fuselage deformation. ( for example 1[3] 2[4] )

The thresholds for 28L/R have been displaced very recently by ~300ft. Furthermore, new glideslopes have been installed/are in the process of being installed.
Aircraft are usually cleared for a visual manual landing to 28L on a CAVOK (nice weather) day like today.
If the Instrument landing system for 28L was active, TCH would have been 64ft.
It appears the aircraft landed short and struck the breakwater; The tailsection including the elevators seperated at the pressure bulkhead (which has been breached) and the aircraft scraped along the threshhold onto the runway proper. The starboard wingtip structure has been destroyed and the aircraft has slid off-runway onto the grass to the left before the first taxiway exit (quite a fast deceleration, it would have come to a stop in less than 3000 ft.) Judging by the position of the impact on the breakwater rocks it's off centre so it seems gear on the starboard side of the main body gear struck it, not the tail section.
At this stage looks similar to BA38[7]
The 747 holding short is United # 885. They're going to be there a long time, I imagine SFO authorities will get a tug to push it backwards along the taxiway sometime later. PAX on the port side would have seen the incident.

looks like some of them grabbed their carry on, I'd be kind of pissed if I was trying to get around someone who was trying to get their luggage

The CNN coverage of this was horrible. They had an "eyewitness" talking about how the plane cartwheeled and the wings separated, and the correspondent was totally going along with it and repeating every word (in case you didn't hear it the first time) trying to make it even more dramatic...meanwhile they're showing live footage of the aircraft with both wings still firmly attached.

One of their "experts" also referred to the fuselage as the hull...I was like OH SNAP...BOAT CRASH AT SFO.

All that aside, it looks pretty much like a blown approach (barring anything mechanical, but with all the people that claim to have seen it happen not one of them reported any sort of smoke or anything coming from the plane). Looks to me (in a completely not professional opinion) that he came in short, realized he was outside the glide slope, attempted to correct by pulling up, and hit the break water with the tail of the aircraft.

I don't have access to it from where I am, but the radio chatter surrounding the incident is all online somewhere, it's pretty amazing how calm the ATC is.

Aircraft and marine use a lot of the same nomenclature and acronyms, a hull loss is considered an aircraft write off for example. Distances are measured in Nm and the officer ranks are same.

Flitght tracker showed what looked like a large anomaly in the entire final approach to the runway - the approach started off way too high at first and then the AC descended very steeply.

A friend of mine had to be evacuated from a flight due to the left brakes setting on fire (only the front right ramp was functioning as the left side was the side on fire, right rear malfunctioned, and right side exits over the wing were too hot to exit from as the engine was very hot after a long flight).

She was saying that it was a disaster because people were trying to bring their luggage and stuff with them. Luckily no serious injuries.

I truly hate people sometimes.

[revelations]

More speculation:

A passenger on a different flight, just prior to the Asiana flight, reported a harrowing approach to a parallel runway at SFO - this all in clear weather.

I wonder if wake turbulence played a factor. The Asiana flight showed an abnormal final approach (high and steep). This is sometimes done to avoid the WT of a preceding aircraft (that arrived in a normal approach path).

Once they were short final, and about the same where the possible WT would still be active, they would have hit the WT.

Ferndale native Margaret Leonardi described witnessing a plane crash Saturday at San Francisco International Airport. On her Facebook page, Leonardi wrote:

Just witnessed the MOST unbelievable thing I’ve ever seen in my life. As my plane landed in SF we hit some turbulence & our plane jolted to the left, turning about 30 degrees before we quickly straightened out-barely making our landing, taking a sharp left & skidding to a stop on the strip between 2 runways. Just as we pulled perpendicular to the incoming runway, we looked up to the left & saw a huge plane (an off duty pilot riding as a passenger on my flight said it was a 777) literally drop from the sky & slam into the ground, almost bouncing it hit so hard. It threw an engine into the center divider that bursted into flames, before the plane turned sideways off the runway & slid until it came to a stop in the dirt. It quickly went up in flames towards the center of the plane & then a few minutes later we saw the emergency slide deploy from the front. No news on passengers. Anyways, long story short Kimberly, they shutdown the airport & nothing is currently coming/going (I’ll keep you posted). Absolutely terrified to board another flight. Pray that everyone gets off that plane!!! — at San Francisco International Airport (SFO).

Sorry but that persons account of their own flight is ridiculous. Landed and skidded to a stop between the runways? I'm gonna go with attention whore trying to make her own flight sound more eventful.

I think she's referring to the high speed taxiway, I've been on loads of flights where you turn off pretty quick onto the taxiway... and then they had to hold before the intersecting runway for the Asiana flight to land so he stopped.

[Go4Long]

yeah...same thing at IAH...they turn off the runway fast to get the heck out of the way because there's another plane coming in right on their ass.

People's description of things when it comes to aircraft is usually skewed too. 30 degrees was probably in the 8-10 degree range. If that, even. Turbulence is always overrated, people see a wing flex 3-4 feet and think it's gonna break.

People that know nothing about aircraft probably shouldn't talk about them.

Yeah she is definitely talking about the high speed exit I just seriously doubt that her flight "skidded to a stop" Her whole description just sounds like a normal crosswind landing

Agreed! When it comes to airplanes for whatever reason, it seems like people who have ridden on one as a passenger become instant experts on the subject.
