🇺🇸 USAF — Project Blue Book
In August 1960, a witness in Littleton, Colorado, observed a white, basketball-sized object with a tear-drop shape slowly descending. The UFO had an arm extending from its upper left side with two internal lights. Although it remained nearly stationary for 20-30 minutes, investigators suggested it might have been Jupiter due to its position and brightness. No conventional explanations or additional witnesses were found, leaving the sighting inconclusive.
