The camera that was attached to the outside of the plane and was pointing into the cockpit has been recovered. The face of the pilot although partially obscured is visible. Pilot was conscious until the very end and perished during initial impact. There does not appear to be any urgency in the pilots actions, which leads to speculation that the pilot might have been confused by the the reflections from the water surface and not aware of the low altitude. Preliminary investigation by Panstwowa Komisja Badania Wypadkow Lotniczych (NTSB equivalent) determined that the plane was fully serviceable and did not suffer any in flight malfunction. Although fuel contamination has not been ruled out as tests are still pending. At this point the main cause of the accident appears to be a pilot's error.
