Atlantic Airways Flight 670 was a crash following a runway overrun of a British Aerospace 146-200A at 07:32 on 10 October 2006. The aircraft's spoilers failed to deploy, causing inefficient braking. The Atlantic Airways aircraft fell over the edge past the runway at slow speed and burst into flames, killing four of sixteen people on board. The investigation was not able to find the underlying cause of the spoilers malfunction. However, it found that disemployment of the anti-lock braking system caused hydroplaning and subsequent reduced braking ability. The damage was aggravated through a minimal safety zone surrounding the runway.
