Looks like Charl said it the other day , as yet no fatalities as yet regarding the type making it the safest to fly on ... it maybe the 894 miles an hour cruising speed that helps dry.gif bloody fact finding reporters rolleyes.gif .... hey! gone the early - nice scheme Asiana had in the 2000s .

No fatalities (as yet), and it looks as if the plane has come in too low and too short, the tail striking the embankment of runway 28L, (the debris starts on the edge of the runway rocks!) snapping off the tail as it struck, then bellyflopping onto the undercarriage which has collapsed and the plane has skidded off the runway. Then it's burst into flames (not surprisingly). FOX journos love to exaggerate!!!! winkyy.gif

Possible it's had the same problem as the BAW 777 at Heathrow? We'll find out soon I guess. Survivors and blackboxes to help prevent it happening again smile.gif

True , and until and only then , its all speculation.
I really dont want to read any ridiculous "conclusions" like those posted here just hours after the Afghanistan 747 incident .

I am superstitious in that way, and after I posted I contemplated removing that comment...
Without going into what might or might not be the cause, there's a witness that saw the plane mush in and tailstrike, followed by cartwheel.
These things are so marginal... a few knots more airspeed, a few more fps vertical...total hull loss.

So those folks that got out, are truly fortunate.

I'm always amazed by people's reaction around a disaster.
Here's a guy having just walked out of the wreck, tweeting a photo.
Minutes later that plane has burnt into a charred wreck - could easily have been his last photo.

Tower transcript: http://wandr.me/Audio/AAR214-KSFO-Crash.mp3

I doubt very much that it is related to the BA777 incident as procedures are in place now to prevent this from happening again.

The issue currently at SFO is that they are doing RESA (Runway End Safety Area) works at the end of 28L and 28R. As a consequence there are no ILS approaches or VASIS's in operation for these 2 runways. It is either an RNAV approach or a LOC for 28R.
All of these approaches are non precision approaches and together with no VASIS can be challenging for some. I would suspect that this was a contributing factor.

Amazing to listen to the tower transcript - the 777 still had power and comms after the "landing"??

True... that BA dead stick landing was truly amazing though, and should've ended differently.
After flying over the North Pole from China, you run out of steam, what 100m? short of the runway. Wow.

As to the photo, plenty of coverage available at KSFO thanks... Me? I'd walk and keep walking before the dam thing blew up.

A good site here for good info.
I suggest reading only the main text rather than user comments. As Splitpin says there is a lot of speculation from armchair experts and some comments can just be plain stupid.

I was the one driving ................ tongue.gif , armchair watchdogs waiting for something to happen rather using the PC for a purpose , rather - new works progress , .. arty side - drawing and editing ... took a break .. started a little jobbie Now another Boeing , the CaptainSim B-52 .. instead of crashing .. get one that dose the smashing .... cool.gif

hey guys, having a look at the pics, i would say the only reason there was a fire in the cabin is where the #2 engine ended up, hard up against the fuselage. the hottest part (exhaust) seems to be resting on or very close to the fuselage, no surprise that it would have started a fire. looks like the procedures worked and a lot of lives have been saved by swift evacuation of the a/c.
again just looking at the pictures, it would seem the left hand side (looking from tail to cockpit) has a lot more damage than the right, suggesting that that side was lower? not trying to find a cause or stir up trouble just my observations as an armchair observer

That's the part that impressed me. The crew of UAL885 had a great view.

I would say for anyone taxiing down the later stages of Taxiway F they would have had a truly trouser changing experience.
Looks like initial (and unsubstantiated) ADS-B data suggests very high rates of descent after commencing approach high. 1400 fpm at 2 miles (if confrirmed) is twice the rate of descent it should be. The SFO controllers do tend to turn you on fast and high. Not a good combo going into a non precision approach (with no vasis) after a long oceanic flight.

Apparently the plane was coming in too low (animation included):

Hell of a ride once the tail had come off ... no shortage of runway and a good example happened in Christchurch with a SA777-200 due strong northwest winds landing on rwy29 , quite impressive to see a 777 over the city like that and got it on the ground .. only issue was it required a tug to push it back to the primary 02/20 for it to taxi .

So now the question is why an experienced pilot aim short , maybe to get off the runway quick or was there a tech prob ... guess he "now be flying a cargo plane outta Hong Kong fill of rubber dog Shite"

Christchurch has plan to extend the 29/11 runway since they own the golf course out the back , prob the next NZCH update .
