... highlighting the need for the pilots to get on the PA ASAP and say something!
with the smashed up avionics bay, were cockpit comms/PA still operational??In the cabin PA was still possible, but maybe this wasn't the case for the captain...

The avionics bay on the 737 is behind the nose gear, so yes it's safe to say the nose gear collapsed in an aft direction!!

Ouch.....

Yes is the FAA going to fine these people for NOT turning off their devices????

Double standards....

When will the riff raff of the world learn to hold their cameras STEADY during crash landings??
Perhaps, since it is a manual control task, they don't get enough training to get it right.
Perhaps we should ask when will the riff raff learn to "turn off all
electronic devices for landing" (or isn't a mobile phone with camera an
electronic device?)
/sarcasm on
Obviously, the use of this electronic device negatively influenced the landing, which is why one is supposed to have them off until the PA announcement is made that they can be turned back on.
/sarcasm off


Volume makes a good point: a landing is the end of a controlled flight maneuver intended to bring the aircraft to the ground safely. Was the impact with the ground controlled? IF not, is it a landing?

On the other hand, any landing you can walk away from ...

If the PF had uncompromised pitch control then yes, it was controlled even if looking back they may have preferred to have done it differently.

Experienced a similar landing, though with less dramatic results, in San Diego many years ago in a DC-9. PF floated it, then dipped the nose to get it onto the short runway, which we then hit somewhat hard. As we taxied off the runway, the CC announced, "Now that we have successfully attacked Lindbergh Field, please enjoy your stay in San Diego."

As we've seen, in the case of the Southwest 737 KLGA nose gear incident, and the Asiana 777 SFO incident, modern aircraft are pretty tough, but I think, testing their limits, should be kept to the testing phases of the development, certification, and subsequent changes to the aircraft in question, and not done while laden with passengers!

How about the airplane's -3deg attitude at touchdown and high rate of descent?

It is interesting comparing the lack of comment on visual landing prowess in this thread with the comments on visual landing prowess in the thread of OZ214 at SFO.

Surely you're not insinuating that the comments might be different were the pilot Korean say?

Ian, the failure mode was different. In one, an approach was never stable, and it was realized (too late) that they need to Go Around. High ROD, nose high. Calling that a landing seems to me a mistake.

In this one, an approach came a cropper in the flare.

Whether or not it was stable up to that point we'll need to find out from the NTSB. If it wasn't stable, then the two events are at least similar in root cause. This one, as SpeedofSound points out, looks to have been a landing ~ a poor one, but a landing nonetheless.

If the 737 was on a stable approach, then the two occasions don't compare very well -- though one does wonder, if the approach was stable up to the flare, why things went pearshaped in the flare. Hopefully NTSB has some info on that.

The rate of info spread, given that it wasn't quite as horrific an impact with the ground as 214, is understandably less pressing.

Flaps setting was changed at T minus 56 seconds from 30 degrees to 40 according to the NTSB, is that normal in a stabilized approach on a 737?

Caused by landing nose first, evidently.

See the post @ 152:

It might be a tad low and late, but I wouldn't think really outside the envelope.

Approximately passing WARIN - 860 feet and 2.5 miles from threshold, assuming 135 kts.

http://flightaware.com/resources/air...C+RWY+04/png/1

I stand to be corrected by a current 737 driver.

4 seconds before touchdown they were 134 kts, flaps 40, pitch up 2 degrees. Which seems fine. It just appears* they flared a bit high - over-corrected - planted the nose.

*videos, NTSC numbers, pilot eyewitness on ground.

Late-ish selection of F40 is not unusual - the limit speed is only 162kts. Doing sums it appears they were fully configured by 500' so would have met the criteria in that respect. Speed sounds in the right ballpark too, though normal pitch angle is about +0 on a 3° slope with F40.

American culture of cowboy hard landings?

Is there a SWA culture of slamming the plane down? Or are there some other American cowboy cultural attributes at play here?
No one needs to answer - I'm just being sarcastic given the amount of drivel about Asians generated in the Asiana thread.

It appears there is a fundamental problem with hand-flying the plane that appears to be increasing in frequency and it appears that the Americans, from whose tail the sun shines, are nor exempt.

I don't see any flare at all in that video, it's flown into the runway rather than onto. I'm trying to picture how any pilot neglects to flare but my imagination fails me.
