The single-motor P47 Thunderbolt went down on February 14 1945, only 10 weeks prior to the end of the war in Europe, at Ottersweier, in the southwestern condition of Baden-Wuerttemberg.
Its destruction was discovered four meters (15 feet) subterranean in a plantation by Uwe Benkel, a beginner analyst in World War II accident destinations, DPA said.
Its pilot was recognized as Antoine Allard, 25, from Paris.
The area of the accident had long been known, and checked by a landmark.
A neighborhood tenant, Werner Doll, now matured 77, depicted how as a seven-year-old chap he saw the Thunderbolt slam into another plane before plunging to earth.
"At whatever point I passed by (the accident site) I generally said a couple words" to the not well featured pilot, Doll said.
German fighters set a French banner and blossoms on the site, to a horde of a few dozen spectators.
Allard's remaining parts will be entombed at a so far unidentified cemetery, the report said.
