September 21, 1950 — Provincetown, MA
MIT research associate and Air National Guard Maj. Myron Herbert Ligda and Joseph V. Connelly are testing radar near Provincetown, Massachusetts, under contract to the US Signal Corps, when they track an unknown object on a converging course with two F-86s. The clear target passes the planes at a speed of at least 1,200 mph, makes a right turn, then passes directly over or under the F-86s. [Eberhart]
