🇺🇸 USAF — Project Blue Book
In April 1950, a witness in Chandler, Arizona, observed a luminous object moving rapidly across the sky. The object was described as round, similar to a balloon or a ping-pong ball, with sharp outlines and a dull color. It traveled from south to north, covering an angular distance of approximately 9 degrees per second. Although the witness initially thought it might be a meteor, the speed and trajectory made him doubtful. Investigators concluded it was likely a bright meteor, visible even during the day. The observation was brief, lasting only 10 seconds, but enough to leave a clear impression of the phenomenon.
The report details that the witness, an experienced pilot, had no doubts about the object's direction or appearance. Despite his experience, he couldn't accurately identify it. The physical description and trajectory are consistent with data from a bright meteor. However, the apparent speed was astonishing. The analysis suggests the object was very far away, which would explain the perceived speed. The report concludes that, although rare, a meteor is the most plausible explanation for the observed phenomenon.
