AirAsia flight to Malaysia landed in Melbourne by mistake
It looked terrible until you realised the flight originated in Sydney and was diverted to Melbourne by air traffic control due to the plane's navigation system having shat itself.
The captain of an AirAsia X flight to Kuala Lumpur on March 10, 2015, inadvertently entered the wrong longitudinal position of the aircraft before takeoff, causing the on-board navigation system to go into a spin while in the air.
And why did it shit itself/ I hear you ask? Because the dumbarse pilot fed incorrect navigation co-ordinates into the system before take off.
But here's the killer sentence:-
"The ATSB also found that the aircraft was not fitted with an upgraded flight management system that would have prevented the data entry error."
