🇺🇸 USAF — Project Blue Book
In August 1957, a witness in Los Angeles observed three round yellow objects forming a triangle. Seen through binoculars for five seconds, these objects moved from east to west. The description suggests they could be aircraft, though a meteor is also mentioned as a possibility. The observer, a jet pilot, estimated a speed of 1200 to 1500 knots and an altitude of 50,000 feet, but the data is inconclusive.
The short duration of the observation and the lack of photographs complicate analysis. Radar data indicates only two objects at 350 knots, partially contradicting the account. Additionally, the witness mentioned his Geiger counter jumped 1000%, though no meter reading was provided. The discrepancy between the observer's estimates and official data leaves multiple possibilities open, but no definitive explanation exists.
