On 29 March 2010, a Raytheon 390 operating a passenger charter flight failed to follow acknowledged taxi instructions in normal visibility at night and entered the departure runway at an intermediate intersection and turned to backtrack against an opposite direction CRJ200 which had just started its take off roll. There was no ATC intervention but the CRJ crew saw the aircraft ahead and were able to stop before reaching it. The Raytheon flight crew stated that they had “encountered considerable difficulties finding out where they were while taxiing and ended up on the departure runway “without realising it.
