jointly by NICAP &
Project 1947 with the help and
cooperation of the original compiler of RADCAT, Martin Shough, to create a comprehensive listing
of radar cases with detailed

Ridge: Another interesting radar "Unidentified" is the case of a UFO tracked by a Massachusetts Institute of Technology radar observer while in the process of conducting a weather radar project (under a contract with the U.S. Signal Corps). An extract from his letter to Major Tuttle, Staff Weather Officer, 33rd Fighter Wing, Otis Air Forece Base, Massachusetts, explains the situation and is provided in the report synopsis by Dr. J. Allen Hynek. Brad Sparks: Sept. 21, 1950; Provincetown, Mass. (BBU 809) 9:53-9:55 a.m. (EST). MIT research associate and Air
National Guard Maj. Myron Herbert Ligda and Joseph V. Connelly (plus
another witness) tracked on SCR-615B radar an unidentified object
heading N, during MIT Weather Radar Research Group tracking of USAF
flight of 2 Otis AFB F-84 jet fighters which were heading 333 degrees
straight and level course at about 400 mph (IAS 250 knots) positioned
at range 45 miles 105 degrees azimuth initially, at 9:50 a.m. Object
detected at 9:53 a.m. on a nearly intersecting straight line course
heading about 358 degrees [at about 500 mph?], F-84 pilots were warned
by VHF-1 radio but could not see object due to poor visibility haze
when ground radar showed object crossed about 3 miles [actually plotted
about 1-1.5 miles ahead and blips "nearly merged" in front of jets at
9:54:00 a.m. Object speed about 1,500 mph as it made a sharp right turn
and loop of about 270 degrees about 15 g's centripetal acceleration
