A mid-air collision occurred over the lake during a United States Air Force exercise on the evening of 3 November 1959.
 A Lockheed T-33 Shooting Star simulated an enemy aircraft approaching from the east while ground-controlled interception directed Convair F-102 Delta Daggers of the 37th Fighter-Interceptor Squadron from Burlington International Airport to intercept it.
 One of the F-102s pressed a simulated firing run too close as the interception occurred over the lake, and the F-102 delta wing cut the tail off the T-33.
 The T-33 crew ejected successfully, but the rear seat crewman died when he became tangled in his parachute and landed upside down near the front section of the T-33.
 The front half of the T-33 was discovered in 1959, and the back half was discovered a few years later.
The F-102 aircraft was discovered in Flagstaff Lake in 1979, but the pilot was never found.
