On 9 August 2012, a serviceable Cobham Leasing Fan Jet Falcon overran the 2291 metre long runway at Durham Tees Valley after beginning a rejected take off from above V1 because of a concern at possible airframe damage from a single medium sized bird sighted ahead which it was subsequently suspected may have been hit by the main landing gear. It was found that the overrun distance had been increased by low friction on the stopway and noted that the regulatory exemption issued for operation without FDR and CVR was no longer appropriate.
