"Sully" was just ice cold. More people should try to be that way instead of losing their heads over nonsense. Dude knew the plane was going down and he totally eliminated his panic mode and did what needed doing.
Also, I would've liked some geese screams to go with the honking when the video showed the flocks of the birds.comment:www.metafilter.com,2009:site.79629-2472315Mon, 02 Mar 2009 14:59:56 -0800BurhanistanBy: peep

Imagine the suck the departure controller felt at "...radar contact is lost."
There's some time compression here, which is unfortunate. The plane departed LGA at 1525, reported the bird strike at 1527. The call to TEB happend at 1529, radar contact was lost at 1530, 32 seconds later, the plane hit the water.
So the whole sequence was close to six minutes, not the the less than two that that this video implies.comment:www.metafilter.com,2009:site.79629-2472326Mon, 02 Mar 2009 15:04:41 -0800erikoBy: joe lisboa

Agreed, Burhanistan. I found myself getting palpably frustrated with the control tower folks reciting alternative runways/airports while the plane was already in the water.

There is pushback on the pure Sully adulation. I was talking to a commercial pilot the other day after he returned from the airline's regularly scheduled training. The pilot said the people running the simulator were getting a bit irked by all the unquestioned and extended praise heaped on Captain Sullenberger without more analysis. They ran the simulator several times for the craft's position, altitude, and flying conditions, and were able to safely make the Teterboro airport runway every time.
Of course, it was a split-second decision based the captain's assessment of the situation, and had the craft landed short of the runway, the results might have been far worse than they were. All the pilots did feel that, for a water landing, he came close to absolute perfection.comment:www.metafilter.com,2009:site.79629-2472409Mon, 02 Mar 2009 15:52:46 -0800mdevoreBy: peep

mdevore: you know what? Thanks. Because now I respect the decision more. It was a hell of a tough call no matter what, and no time to weigh pros and cons. Yet in a split second, he decided that with the real possibility that he and everyone else on board was doomed no matter what he did, he could at least choose to minimize risk for people on the ground. A principled decision, with the determination to make it work out for all. I suspect most of us would've chosen whatever route offered the best odds of self-preservation, and just crossed fingers for the folks on the ground. "Oh is that a jet engine dropping on your head? We're terrible sorry but it was unavoidable..."comment:www.metafilter.com,2009:site.79629-2472431Mon, 02 Mar 2009 16:12:46 -0800nakedcodemonkeyBy: turgid dahlia

Well, if they <em>know </em>what they're going to do <em>before </em>they strap in, <em>of course</em> they'll find an elegant way to do it. And they'll learn something doing it, which is good.
It would be more interesting to "surprise" someone in the simulator by throwing a replay of the 1549 situation at them, to really see what other pilots decide to do.comment:www.metafilter.com,2009:site.79629-2472471Mon, 02 Mar 2009 16:52:40 -0800Cool Papa BellBy: notsnot

It's easy to jump out of the way of a bus that's bearing down on you if you know it's going to be coming in advance.

I think Sully took the water because in that split second he could not take the risk of wiping out even more people on the ground. If he fucked it up that would be a very high risk in NYC.
Turgid Dahlia, it's not a crash when you land without dying in the water, it's a ditch. Sully managed the first successful ditch in aviation history of a commercial passenger jet. I think it was a good decision though -- he had perfect conditions, extremely still water and more room to set up the ditch than he would have had for a landing at the airport he could barely reach.

The animators edited so much out of the audio track. The <a href="http://www.youtube.com/watch?v=MSPsrhCPt-0&feature=channel">original audio recording</a> is even more interesting, with controlled chaos unfolding on one end, and even swifter decisionmaking on the other. It's amazing how everyone manages to get so much done within a span of only 2-3 minutes. Sullenberger is already contemplating the ditch option a mere *40 seconds* in. Wow.
The controller keeps on crisply working to find them a safe landing, even after they've dropped off radar and he's convinced (as he later admitted) that the lot of them are already gone. Hard not to tear up as you endure the radio silence with him. Must have been hell.comment:www.metafilter.com,2009:site.79629-2472537Mon, 02 Mar 2009 17:59:31 -0800nakedcodemonkeyBy: joe lisboa

Stories said he was furiously trying to restart engines, which is a complicated checklist of procedures, and only some items can be skipped safely in a pinch. If he had managed that feat (and he couldn't have, because of the damage, but he didn't know that at the time), they almost certainly wouldn't have had to ditch. And ironically, we probably wouldn't have ever heard about his heroics in doing so.comment:www.metafilter.com,2009:site.79629-2472660Mon, 02 Mar 2009 20:51:58 -0800Cool Papa BellBy: dhartung

<i>What does the blue know about Captain Skiles' role? I am under the impression that it takes two people to land the plane - Surely Captain Skiles was doing something, right?</i>
Skiles was co-pilot and flight engineer, and I'm sure he had plenty to do. He may have been trying to restart the engines.
Ever since the <a href="http://www.airdisaster.com/special/special-pa1736.shtml">Tenerife</a> <a href="http://www.youtube.com/watch?v=utAj1Tf9nsQ">disaster</a><a href="http://en.wikipedia.org/wiki/Tenerife_disaster">^</a>, which was partly attributed to the pilot overriding the concerns of a co-pilot, commercial aviation has emphasized <a href="http://www.psychologymatters.org/crm.html">crew [or cockpit] resource management</a>. The idea is that there are three professionals up there and you need everyone's knowledge, skill, and input in a disaster situation. Sullenberger being a safety expert -- he has actually designed a CRM course -- I don't doubt that he and Skiles were equally responsible for the outcome.
They only had two minutes, not enough time for an argument. The decision to decline Teterboro and choose the Hudson was probably one that he at least checked with Skiles with a nod.
<i>but Jeffrey Skiles, the first officer, pretty much gets no credit</i>
Oh, here in Wisconsin, he's gotten some honors, and the entire crew has been honored e.g. at the Superbowl. He seems to be <a href="http://www.veronapress.com/main.asp?SectionID=2&SubSectionID=2&ArticleID=1167&TM=25481.35">fine with the way things are</a>.
<i>I think Sully took the water because in that split second he could not take the risk of wiping out even more people on the ground.</i>
Sullenberger has <a href="http://www.foxnews.com/story/0,2933,488491,00.html">confirmed</a> that the risk of landing in a populated area was a key reason he chose the river.
<i> If he fucked it up that would be a very high risk in NYC.</i>
Well, Teterboro is in Jersey, so who cares?

<i>They ran the simulator several times for the craft's position, altitude, and flying conditions, and were able to safely make the Teterboro airport runway every time.</i>
Sure. Looking at the distance flown, if AWE1549<sup>0</sup> had turned to Teteboro within about ten seconds of the loss of power, they could have made it.
The problems:
1) It takes time to understand the situation. First thought would have been "engine out." It would have taken a couple of seconds to realize multiple engine out. All of that happened *before* the first call about the bird strikes
2) the PF is primed to return to departure airport in the case of power loss on climbout. And that's exactly what he decided to do at first "this is uh<sup>1</sup> cactus fifteen thirty nine<sup>2</sup> hit birds we lost thrust in both engines we're turning back towards Laguardia".
Later, he think about TEB, but at this time, he's out of airspeed, altitude and ideas.
A similar case was AA191 in Chicago, where an engine loss<sup>3</sup> led to damage to the leading edge slats on the DC-10 they were flying. Per procedure, they throttled back the remaining engines and tried to turn back. They didn't know that the slats on only one of the wings were working, so they didn't know that they had different stall speeds for each wing. They throttled back to stall +10 kts, per procedure -- and the damaged wing stalled, they flipped over and crashed.
In the simulator, they found out that if the flight crew hadn't followed procedure, and kept their speed up, they could have made it back to ORD.
So it doesn't surprise me that if you know what's going to happen, and what exactly is wrong wit the aircraft, you can get a better outcome. The good news here is that they did find a better outcome. Now, they'll look at procedures. Because of AA191, the procedure now for engine loss/out at T/O is to keep your speed *up* until you can evaluate for other damage.
I would be surprised to see new departure charts, with little notations like this....
EMERGENCY ON TAKEOFF
LGA 4 RETURN LGA
LGA 14 <b>DIVERT</b> JFK
LGA 22 <b>DIVERT</b> EWR
LGA 31 <b>DIVERT</b> TEB
... and a procedure change as part of the takeoff checklist where both pilots acknowledge what they're going to do if there's a problem at climb out.
0) Those wondering why this is AWE1549, not US1549, and why the call sign is "cactus fifteen forty nine", USAir and America West merged to form US Airways. Though the logo is USAir's, the call sign is AW.
1) These guys change call signs on every flight. It's not uncommon for them to have to look it up, which is why there's a spot on the panel for the current callsign to be written on.
2) And they still get it wrong sometimes. Even more amusing is when NY Departures calls LGA to warn them, *he* gets it wrong too "it's fifteen twenty nine he, ah, bird strike....he is returning immediatly.:
3) They found it lying next to the runway.comment:www.metafilter.com,2009:site.79629-2472951Tue, 03 Mar 2009 07:06:50 -0800erikoBy: spikeleemajortomdickandharryconnickjrmints

<i>Holy schnikees, it didn't occur to me that this was even possible </i>
On a fixed wing, it's not, but airliner wings aren't fixed. They have leading edge slats and trailing edge flaps to change the airfoil. Slats and flaps extended, you get more lift, so your stall speed drops, but more drag, so you're not as efficient.
So, low and slow, you have flaps and slats out, and you don't fly fast, because of the drag. Up high at cruise, they're retracted, you have a very low drag airfoil -- but it stalls at a higher speed.
After AA191 lost the engine, damage to the wing caused the (IIRC) left wing slats to retract. Thus, they had the leading edge of one wing in takeoff/landing configuration, and the leading edge of the other in cruise configuration -- with the lower drag, but higher stall speed.
It killed them. Dropping the engine, really, was annoying, they had more than enough power to take off, circle, and land. But they didn't know that they had a differential stall problem, they slowed down (per the book!) and they fell out of the sky.
This is why the NTSB tries to find *every* contributory cause in a crash. What caused the emergency was AA Maintainence cheating on engine work, damaging the mount. What killed them was a combination of differential stall and the emergency engine-out procedure that they'd been drilled to follow.
That's why they'll look very carefully at this. Currently, everyone says "power issues at climbout, return to departing airport." Maybe that needs to be rethoguht, before the next plane has to use Lake Michigan or the Hudson -- or find that there's no river at all, just trees, or rocks -- or buildings.comment:www.metafilter.com,2009:site.79629-2473993Tue, 03 Mar 2009 20:07:28 -0800eriko
"Yes. Something that interested us yesterday when we saw it." "Where is she?" His lodgings were situated at the lower end of the town. The accommodation consisted[Pg 64] of a small bedroom, which he shared with a fellow clerk, and a place at table with the other inmates of the house. The street was very dirty, and Mrs. Flack's house alone presented some sign of decency and respectability. It was a two-storied red brick cottage. There was no front garden, and you entered directly into a living room through a door, upon which a brass plate was fixed that bore the following announcement:¡ª The woman by her side was slowly recovering herself.

As a rule, ornament should never be carried further than graceful proportions; the arrangement of framing should follow as nearly as possible the lines of strain.

The exhibition of domestic discord and hatred in the House of Hanover had, from its first ascension of the throne, been most odious and revolting. The quarrels of the king and his son, like those of the first two Georges, had begun in Hanover, and had been imported along with them only to assume greater malignancy in foreign and richer soil. The Prince of Wales, whilst still in Germany, had formed a strong attachment to the Princess Royal of Prussia. George forbade the connection. The prince was instantly summoned to England, where he duly arrived in 1728. "But they've been arrested without due process of law.
