Delta Plane Skids Off Runway at LaGuardia Airport
An aircraft skidded on the runway at LaGuardia Airport and crashed into a fence ... It wasn't clear how many people were on the Delta plane when it slid off the runway (www.nbcnewyork.com) Más...NTSB issues 2nd report about Delta accident at LaGuardia
Well, putting a lot of the speculation aside, here is the 2nd update on this plane and then you can probably navigate around the website and find some more but to make a long story short, regardless of what those ahead of him said, the runway turned white and he lost control. NTSB Issues Second Update on the Delta Flight 1086 Accident at LaGuardia
There was a posting on FA a little while back about "crab landings". If you don't hit the runway parallel and it is slippery, it could be a wild ride. It appears from the report that they did not go straight toward the berm, but were parallel to it(they took out 1000 ft of fence). It may not been a good landing, but it was some damn good driving. Maybe NASCAR is in their future. Great job of getting stopped!
There's no indication of direction upon touchdown and rollout but the tracks upon excursion were 10º off runway heading. From what I've been able to glean from some photos along with using a taxi diagram and Google satellite, it came to a rest on the angled part of the berm just east of what appears to be drainage lines and across from Lima. Photos showing Kilo intersecting with Alpha behind the plane. That falls in line with the left wing hitting the berm with such force to shear off.
As for getting stopped, that berm was the only thing that saved them. In the snow, they had no control whatsoever. Once they left the runway, the rest was pure luck.

Well, it was a link on their website
"At the time of landing, when the reversers are deployed, the MD-88’s rudder is not powerful enough to turn the aircraft in either directions and cause a crash, which is why investigators have turned their focus on to the braking system on the aircraft. The federal regulator is investigating whether a possible greater pressure exerted by the brakes on one side of the plane caused the aircraft to steer off the center of the landing strip".
Just think of trying to stop a vehicle with only front brakes. The rear can easily slide to one side. Stop with rear brakes and the front will naturally go straight. In rear engined aircraft the same applies. If both buckets were out and engines spooled, the nose would have gone straight down the runway. I would look into reverse thrust also. There's a safety mechanism to prevent one deploying without the other but what about failures?
