Bad luck for a sergeant

The Spanish Supreme Court has set aside the acquittal of a sergeant on charges growing out of a 2007 parachuting accident in which a soldier was put into a vegetative state. The court ordered a retrial because the military trial court disregarded two experts and relied instead on testimony that even if the sergeant's jump calculations had been correct, there's always the chance of bad luck. The victim's father had appealed the acquittal to the Supreme Court. Details here.
