Project Blue Book Case File
Danforth, IllinoisAugust 1947
Summary
In August 1947, a farmer near Danforth, Illinois found a collection of metal and ceramic fragments on his land. He reported that the object had landed in the middle of his field and burned weeds up to 23 feet tall, charring them to ash across a circular area approximately 15 feet in diameter.
The package containing these fragments was forwarded to the U.S. Air Force Materiel Command at Wright Field, Ohio for analysis. Technicians examined the items carefully to determine whether they had any connection to the "Flying Saucer" sightings that were making headlines at the time. The collection included fragments of plaster of paris (a type of molded ceramic) mixed with electrical resistance wire, an outdated magnetic speaker diaphragm manufactured in 1910, old bakelite coil forms wrapped in copper wire, a filter condenser, and parts of a metallic magnetic device. The Air Force Analysis Division concluded that none of these components matched any classified research project in development at their command.
The Air Force's final assessment was straightforward. Investigators determined that the specimens showed signs of crude assembly by someone unfamiliar with engineering or electronics work. The analysts stated that "these specimens are considered as part of a hoax that could be perpetrated by almost anyone seeking publicity or for other reasons." The Air Force recommended that if similar objects were found elsewhere in the country, they could be evaluated using this case as a reference.
