SMS to mobile could be the cause of plane crash

"But investigators have not ruled out cellphone interference after reports that a family member of one of the dead passengers had sent a text message to someone on the flight. On Christmas Eve 2000, a plane approaching Wellington at 1400ft (426m) suddenly turned right and climbed. The crew went to manual control to correct the flight path. It is suspected a passenger's cellphone rang during the approach. All other possibilities were rejected."

This is all linked to an article published before, about a study by the British CAA (Civil Aviation Authority) about mobile phone interference in flights.
