Crashed January 18, 1972, whilst on a routine ground controlled approach to RAF Leuchars, crashed approximately 975 ft on a snow covered 1,050 ft high mountain in the Sidlaw Hills, near Burrelton, Perthshire, Scotland, approximately three-and-a-half miles south of Coupar Angus, and 15 miles north west of Leuchars.
Both crew - LT COL Floyd B. Sweet (pilot) and LT COL Kenneth T. Blank (WSO) - were killed, as no ejection appears to have taken place
Lt COL Sweet had been the 77 TFS, Director of Operations. The 77th named the squadron bar in his honor "Sweet Floyds." To this day the 77 FS, now at Shaw, has their heritage room named after Lt COL Sweet with the original plaque from the 77 TFS bar at RAF Upper Heyford.
