Delivered October 18, 1966, this was Pilgrim Airlines' first Twin Otter. One of 15 either purchased, leased or acquired in the merger with Newair in 1985. Pilgrim was itself bought by Business Express Airlines and merged in February 1986. The Twin Otters were retired with N121PM being withdrawn in March. Sold in 1986, the aircraft has been flying for Skydiving schools ever since.
