Tanker 498 gets fire retardant stains removed while standing down during British Columbia's 2017 fire season. Originally delivered to Eastern Airlines (N5525) in 1959, the Electra spent another 30 years flying freight before Air Spray bought it in 2011. First registered C-GKIL, Buffalo Airways cancelled the registration on their DC-3 C-FDTH to make it available to Air Spray in 2012.
