A 40-year old Kansas City area man is in custody after allegedly breaking through the locked cockpit door of an Alaska Airlines flight last night. Joe Riley, a sergeant with the San Fransisco police department, says passengers and crew wrestled the man, Peter Bradley of Blue Springs, to the floor after he broke into the cockpit. Riley says Bradley had been unruly before breaking into the cockpit, trying to take his clothes off, upgrading himself to first class and even threatening to kill everyone.
