The whole UFO case report:
Fran Ridge:
In May of 2005 we found MAXW-PBB9-1289 (an AIIR, Air Intelligence Information Report) while looking for something else. Since I was working on White Sands cases I set it aside. Then, a week later, I stumbled across another reference. NARA-PBB85-654 mentioned an unidentified radar return. It was marked with brackets as secret. However, it was listed as having occurred on April 8th at 2000 hours (8:00 PM). I checked the NICAP Db and it wasn’t there, so I then went to the ‘Bluelist’, the outdated PBB Unknowns. Duncanville was listed, as Item 1095, and as April 5th. But Dan Wilson & Brad Sparks had noted the correct date as April 4th.

Brad Sparks:
April 4, 1952.  Duncanville, Texas (BBU 1095)
8:30 p.m. (CST)  USAF Cpl. Billy D. Greer and PFC John W. Harrington of the Radar Maintenance Section, 147th AC&W Squadron, tracked unidentified target by FPS-10 radar first to the NW at 310°-315° azimuth at about 70 nautical miles (80 miles) moving at high speed of about 2,160 knots (2,500 mph) until it disappeared off the scope at maximum range of 260 n.mi. (300 miles). Height-finder reading not taken, estimated at 42,000+ ft due to radar beam coverage at max range.
