On 9 May 2011, a Bombardier Challenger 850 began a positioning flight night take off from Dubai aligned with the right hand edge of runway 30 for which take off clearance had been given. The error was not detected until a collision with a lighting installation after which a high speed rejected take off was made. The Investigation noted that the Captain had lined up the aircraft on the runway edge in good visibility before passing control for the take off to the low-experience First Officer. It was concluded that the crew failed to sufficiently prioritise their external situational awareness.
