Apparently, they were cleared to land on 19R even after confirming with ATC the runway was indeed open (as a Notam indicated its closure). They hit the first obstacle at about 130 knots then a second one. They lost the nose and left main gears and skidded off the left side of the runway. I have seen the aircraft myself: all engines are still attached with #3 and 4 apparently intact but #1 and 2 have suffered damage. There is no sign of fire (as far as I can tell: I never got closer than 200 meters...). The ATC on duty fled the scene and was arrested the following morning...
Glad they are all ok.
Cheers
