During a private “fly-in” fishing excursion in the [Alaskan] wilderness, a chartered pilot and fishermen left a cooler and bait in the plane. A bear smelled it and destroyed the plane.
After a few days of meticulous fix-it work, the plane was airworthy enough to fly back to Anchorage. Miller fitted the windows with plywood and Plexiglas, replaced the tires and the horizontal stabilizer (the bear either leaned on it or sat on it), and, according to Miller’s dad, fashioned a makeshift fabric skin out of 25 rolls of duct tape and some industrial-strength plastic wrap.
