415th Night Fighter Squadron 'Foo Fighter' encounters — Rhine Valley, December 1944–January 1945

Sortie reports from the 415th Night Fighter Squadron compiled January 30, 1945 document multiple encounters by pilots with unexplained aerial lights during December 1944 and January 1945 over the Rhine Valley. The reports describe lights blinking on and off, changing colors, flying in formation with aircraft, following planes when turned toward, peeling off and then returning, and in one case staying on an aircraft's tail for approximately two minutes before pulling up rapidly. In every instance where pilots queried GCI Control for enemy aircraft in the area, they received a negative reply. The phenomenon was named 'Foofighters' by combat crews. This file also contains a related SHAEF/Allied Expeditionary Air Force document from March 1945 reporting a sighting of a cylindrical aluminum-colored object approximately 12 feet long and 1 foot in diameter floating at 9,000 feet, which was attacked and partially deflated without disintegrating.

“We have encountered a phenomenon which we cannot explain; crews have been followed by lights that blink on and off changing colors etc. The lights come very close and fly formation with our planes. They are agitating and keep the crews on edge when they encounter them, mainly because they cannot explain them.”

Multiple sortie reports spanning December 1944 through January 1945; individual dates extracted from sortie records. OCR quality is moderate but key passages are legible. The cylindrical object sighting (March 1945, 9,000 ft, F-5710 area) is from a separate but related SHAEF signal — photos attempted by 107 Squadron of 67 TAC/R Group were unsuccessful. Air Ministry assessed some phenomena as possibly Me 262 or 'flak rockets' but acknowledged the matter remained a mystery. GCI consistently reported no enemy aircraft in vicinity during encounters.
