while the controller may have been partially to blame, the Ryanair pilots are also to blame reading that. It states the Ryanair plane was taxying at high speed to the terminal when it proceeded onto the runway. Well firstly he would have been required clearance to cross the active runway, and without scripts its impossible to tell if he got them, secondly he should have done a visual inspection of the runway before crossing, and since the weather was clear he would have seen the plane comming towards him on the takeoff roll. Many more people to blame than just one controller.
