Nicholas Tiffany wanted his dad to have a shot at the KR-21, so he removed all the flyers that owner Mike Butler had posted except one, which he presented to his father. Jack Tiffany bought the airplane and spent three years restoring it with his partners. The wings were the biggest challenge: They are tapered and no two ribs are alike. “Rib number 3 on the left side wouldn’t fit on the right,” he says.
McNerney had also looked at a Waco biplane, but the KR, he says, “is a little more delicate than the Waco, and the cockpit is huge. Compared to a Great Lakes [biplane trainer], it’s like sitting in a hot tub.”
