A U.S. Air Force F-15 pilot shot down near Iran last June told investigators directly he saw drones move in unusual, bunched patterns.
He described it like sea tentacles flaring then contracting.
Iran has not responded on the report.
Stories picked up it on The Times of Israel, WION, MSN and Anadolu Ajansı.
The sighting fits into larger fights between the U.S. and Iran in the skies.
