A man with a pistol, later determined to be a starter's pistol, forced his way aboard Finnair Flight 509, a DC-9 aircraft, at Oulu, Finland, as it was preparing for departure to Helsinki with 95 passengers and five crew members. The hijacker described as being mentally disturbed, released all the passengers within a half hour but continued to hold the crewmembers.
He did not state a destination for the aircraft but demanded that a television crew be brought aboard the aircraft to publicize a statement about the treatment of psychiatric patients in Finland. Police officers, disguised as television crewmembers, boarded the aircraft and apprehended the hijacker. There were no injuries during the incident.
