Runway excursion. On 11 August 2010, a Douglas DC8-63F being operated by Afghanistan-based operator Kam Air on a non scheduled cargo flight from Manston UK to Sal, Cape Verde Islands failed to get airborne until after the end of departure runway 28 during a daylight take off in normal visibility. The aircraft eventually became airborne and climbed away normally and when ATC advised of the tail strike, the aircraft commander elected to continue the flight as planned and this was achieved without further event. Minor damage to the aircraft was found after flight and there was also damage to an approach light for the reciprocal runway direction.
