The A340 was being towed into a hangar. A staffmember, who was tasked with placing chocks on the main-gear wheels, approached the aircraft before it had come to a complete stop and was "caught" by the gear and dragged under it, resulting in both legs being crushed and in need of amputation below the knees.
At an age of 58, and considering SAS hasn't hired for years, one can safely assume this was a very experienced staffmember. Only goes to prove that experience is no match for complacancy and that, sometimes, experience breeds complacancy. It's almost never the FNGs who're having accidents; it's "always" the old and experienced hands.
