At the time of this photo Everts operated the largest fleet of Douglas DC-6s in the world, and ten years later they were the world's last commercial operator of the type. This former Sis-Q aircraft N555SQ (Tanker 45) was was originally delivered to United Airlines in June 1957 as N37585. Everts acquired it in 1994 and operated it for 18 years until withdrawn from use in 2012. It is now stored at Fairbanks, AK and used for spares to keep the rest of their fleet in the air.
