Brad Sparks had this one listed briefly in his catalog: "May 13, 1955; Duluth, Minn. (BBU) 8:30 p.m. (CST) (McDonald list)"  The documents I located give the following details. Two airmen flying in a F-89D at 26,000 feet on an air intercept mission locked onto an object on the RO's radar scope. The target was at 8 miles distance and move to 6 miles distance. The target moved to within 6000 yards and stopped dead. The object immediately began going out in range faster that it came in. The estimated speed at the time target indication was going out in range, according to scope interpretation and pilot's and RO's experience in running interception, would be over 1000 knots. Air-electronics: APG-40; APA-84 Observers were: 1/Lt. Charles M. Middleton, pilot, and 2/Lt. Donald. G. Fisher, radar observer, both of the 11th FIS, and both rated as completely reliable.
