At about 18:08 EST, the pilot of an experimental Zenair 601 lost control on landing rollout and crashed at Kissimmee Municipal Airport. The two occupants were uninjured. The flight originated from Winter Haven, Fla., about one hour eight minutes before the accident. The pilot said he departed on a local flight and became disoriented and lost as it got dark. He observed a city in the distance and flew toward it, figuring he could find an airport. As he approached the city, he saw a runway and entered left base without contacting the control tower. He lost directional control of the airplane on touchdown and the airplane went off the side of the runway and collided with a barricade.
