Prior to DEPARTURE, the pilot had obtained a weather briefing, which indicated that deteriorating conditions were forecast. This forecast proved to be accurate and the pilot was forced to carry out a number of diversions to remain in visual contact with the ground. The fuel state of the aircraft also became critical, and in the face of further deterioration in the weather conditions, the pilot attempted to land on a racecourse. A normal touchdown was made, but the aircraft slid off the banked track and collided with the inside guard rails.
