A U.S. Air Force F-15 pilot shot down over Iran last June told investigators briefly he saw drones move in unusual, clumping patterns.
He described it like jellyfish tentacles expanding then contracting.
Iran has not commented on the report.
Stories reported it on The Times of Israel, WION, MSN and Anadolu Ajansı.
The sighting fits into bigger fights between the U.S. and Iran in the skies.
