10/31/2013. Remarks by Johan Visschedijk: "This modified Learjet 35A was the prototype of the Sea Patrol special mission version of the Learjet 35A/36A. First flown (site files) in spring 1979, it was exhibited at the Paris Air Show in June and at Farnborough in 1980. The Sea Patrol model was suitable for the location and detection of surface vessels, the identification of targets and determination of target activities. Three very similar equipped Learjet 35As were sold to Finland in December 1980."
