While passengers were boarding Swissair Flight 125, a DC-10 flying from Chicago-O’Hare International Airport to Zrich, Switzerland, a man with a knife ran past the gate attendant, down the jetway, and onto the aircraft where he grabbed a female passenger and held the knife to her throat. The hijacker was not ticketed on the flight and the knife was later determined to be a pocket-knife. He shouted in broken English that he wanted to go to Switzerland and, in later interviews, said that he wanted to seek help there in having his films produced. After approximately 25 minutes of negotiations, the hijacker released the female passenger he was holding hostage and surrendered his knife to the police. He was arrested and charged with air piracy. The hostage was injured in the incident.
