Sorry folks but I read the " causes" part as shown in the web site more as a total failure of the Airline in providing training, proper CRM, and in distribution of essential info to their crews, rather than just " Pilot error " .
Of course it will always ultimately be the guy at the control who screw things up, but why and how did he arrive to this is the crucial question.
I guess some heads are going to roll at Luxair if what we read in the web site is indeed in the final report .
This sounds very similar to the collision in July 2002 in Ueberlingen.. first blame the persons at the controls,( Swiss controller or even Russian pilot ) but the failures were largely in management as the final report will show.
