The evidence for the pilot’s ill-advised actions is circumstantial. His airplane, a Cessna 150K, had a GoPro video camera mounted on the glareshield. The day before the accident, he took several friends flying, and the GoPro recorded both them and him photographing things, including themselves, with their cellphones. The accident took place that night, shortly after midnight. At Denver’s Front Range Airport, the pilot made a flight around the right-hand pattern with one passenger, during which the GoPro was again running and recording the pilot as he snapped a selfie. The camera’s flash fired, illuminating the cockpit. The pilot then landed, embarked a new passenger and took off again. The 150 began the right crosswind turn, but then gradually rolled left into a tightening spiral, its vertical speed increasing to 1,900 fpm. The left wing was the first part of the airplane to strike the ground.
