Delivered to Skymark Airlines in March 1968 as N952SM, this Twin Otter flew with various commuter airlines until 1986. With Pilgrim Airlines at the time, that airline was acquired by Business Express in February 1986. The aircraft was quickly withdrawn and stored at Groton, CT. Sold to Free Fall Express in the summer of 1990, it switched to flying skydivers and is still current at the time of uploading.
