🇺🇸 USAF — Project Blue Book
In December 1957, a witness in Indiana described a round, white object the size of a grapefruit. The object was moving very slowly and remained visible for 30 to 45 minutes. Although the possibility of a balloon or astronomical phenomenon was mentioned, the data was insufficient for a conclusive evaluation. The description does not include additional details or images, making further analysis difficult.
The report, though brief, reflects the typical uncertainty of many accounts from that era. No other related report was found in the files, suggesting that this case was not investigated beyond the initial record. Despite the lack of information, the testimony remains an interesting example of how sightings were documented in the 1950s.
