Analysis
The purpose of the flight was to fly over a lake and observe alligators. A witness observed the biplane diving at the lake and pulling up multiple times. On the last pull up the airplane slowed and entered a spin at an altitude too low to allow for recovery. The airplane collided with the lake.
