Do you like seeing the ridges and valleys of mountains from above when you’re flying in an airplane? Well so did Reuel Call, who founded the CallAir Airplane Factory with his brother, Spencer, and uncle, Ivan. The fixed-wing, single engine aircraft you see here was developed by the Calls, Wyoming ranchers who wanted to take spins around the mountains and needed an airplane that could get in and out of tight spots. Spencer’s wife, Pamela, wrote in her memoir, “they didn’t know they were making history.” In 1946, the CallAir A series aircraft debuted. It was “noted for its performance on short, high altitude runways,” and could be used as a passenger plane or as a spray-plane for crops. Writer Joseph Juptner described the CallAir as “inherently stable, easy to fly...and sure footed as a mountain goat.” It came equipped with both wheels and skis for summer and winter flying. Those skis would come in handy on a bitterly cold day in 1949, when Charles Wyman flew this exact CallAir to a farm where the expectant Mary Reiner and her husband, Peter, were stranded. Peter had set a hayfire to guide the pilot to the farm so that Mary could be escorted to a Dickinson, ND hospital, where she gave birth to her daughter, Patricia, on March 17, 1949.
