🇺🇸 USAF — Project Blue Book
In July 1966, a civilian observer in Port Harrison, Canada, reported a balloon-shaped object with cords hanging down and a small attached object. The object was moving slowly southwest at about 20,000 feet for two hours. Although the specific balloon could not be identified, experts concluded it was likely a weather balloon. The description matched typical meteorological balloons launched in the region, even if none could be directly linked to the sighting.
Authorities checked several balloon launch centers in the area but found no matching records. It was determined that there was no national threat or significant scientific benefit to justify further effort. The case was closed without further investigation, highlighting the challenges of tracking unidentified aerial objects during that era.
