here's something to start you off

On March 2, 1965 in Brooksville, Florida a John F. Reeves, 65, retired, was walking in the woods when he observed an object10 m in diameter, 2m thick, saucer-shaped with an outer rim and a stairway. After watching it for 10 min, he saw a robot-like being, about 1.30m tall, wearing a silver uniform, glass headgear, and then returned with a box that emitted a flash when pointed at the witness. The object subsequently took off with a whistling sound.
