Kjeller PK X-2


Four-seat prototype helicopter developed by Kjeller Aircraft under the leadership of Lt.Col. Paul Kjølseth of the Royal Norwegian Air Force. It was powered by a 800shp General Electric YT-58 turbine engine and first flew in 1960. Project was abandoned February 9, 1965, when technical problems forced the funding to cease, prompting Norway to import helicopters for service instead of developing indigenous types.

Also said to have first flown in 1962. Which is correct?
