I remember one C172 I think, over ran the strip and overturned into the dam. It was on a race day in about 1977, a Sunday from memory. We had departed MB for DPO and being heavy passed over CWS VOR at about A055. Whilst sticky beaking at the races we noticed the 172 on short final and watched it land. We notified ML FS, although there was plenty of rescuers and equipment on site.
