Project Blue Book Case File
County Darmstadt near Frankfurt, Germany, March 1961March 1961
Summary
In March 1961, a civilian witness in the Darmstadt area near Frankfurt, Germany reported seeing an unusual object in the sky. The witness observed it through 12-by-50 binoculars and watched as it changed color, starting bright white, then turning red and orange, and changing back to white. The object appeared to move in an irregular path: toward the right, upward, then toward the left. The file does not provide the exact duration of the sighting or the total distance the object traveled.
The case record form mentions that the object was generally round and changed color as it moved. An Air Force analyst suggested several possible explanations: a weather balloon, the moon, or the planet Jupiter. The investigator noted that the witness had been asked to provide additional information but had not replied by the time the file was compiled. The Air Force determined there was no evidence that the object presented any threat to U.S. security. The file does not specify a final conclusion about what the object was, though the analyst's comments suggest weather balloon or astronomical phenomena as likely explanations.
