On 11 March 2013, at night, a Sunwing Airlines' mechanic left their vehicle on the ramp with the engine running and in 'drive' and, unseen, it began moving towards the adjacent runway threshold, at which point ATC noticed a ground radar target and instructed an Air Canada Embraer 190 which was close to landing in accordance with a valid clearance to go around. The pilots did not hear these instructions and landed directly over the vehicle with approximately 35 feet clearance without seeing it.
