According to passenger accounts in the media, the attempted hijacking began shortly before the Boeing 737 plane was going to land in Istanbul on Wednesday. The masked suspect, later identified in news reports as 40-year-old Yasar Cuma or Cuma Yasar, claimed to be holding a bomb (later found to be fake) and tried to break into the cockpit, demanding that the plane return to its originating point in Oslo, Norway.Good thing for him he wasn't heading to the US or he would have been caught by the TSA. As soon as the plane entered US airspace.
