The Finnair operated Sud Aviation Caravelle with 44 passengers and 5 crew aboard was hijacked by an unemployed home building contractor.

After forcing the pilot to fly to Amsterdam, Netherlands, and Helsinki, the hijacker received his ransom demands and released his hostages.

[1] Aarno Lamminparras, a 37-year-old unemployed home building contractor who had recently declared bankruptcy, boarded the aircraft in Oulu.

Since Finnish airports did not perform security checks on domestic flights,[2] he was able to carry a loaded Walther 7.65mm pistol aboard.

[3] Lamminparras subsequently forced the pilot to fly back to Oulu where the aircraft circled the airport for several hours before landing to refuel.
