November 23, 1948 — Bavaria, Germany
10:20 p.m. The first documented ground radar–visual UFO case takes place at Fürstenfeldbruck Air Base [now closed] in Bavaria, Germany. A UFO is seen circling at 27,000 feet. An F-80 pilot sent to intercept it describes it as bright red. It climbs abruptly to 50,000 feet at 900 mph. A second F-80 pilot verifies the report. [Eberhart]
If this is the first documented ground radar-visual UFO case, are there any earlier documented cases where UFO was recorded by some other types of radar?
I think it’s just that its the first case documented under the new Project SIGN. I think there were earlier radar-visual cases (like during the war). There was just not a ‘UFO’ project back than documenting them.
