This Beech 99 was delivered to Wright Airlines July 10, 1969, the same year that Cascade Airways was founded in Washington state. Cascade acquired the aircraft in June 1973. It was sold to Beech Acceptance Corp in 1984 as the airline took delivery of Beech 1900s.
Former USAF 53-8153 registered to J. D. Gifford and Associates February 1981. Not a great day in Arlington for photography, but I never saw this Boxcar again. On September 7, 1981 N8504W was landing at Dahl Creek, Alaska when the right main gear collapsed and was substantially damaged. Luckily there were no injuries, but the aircraft was hauled away, broken up and the remains burned.
