Jellyfish formation? This description is too sci-fi. When did Iranian drone technology evolve to this level?

Coinworld news, citing CNN, four sources revealed that a U.S. F-15 fighter pilot shot down over Iran in April recalled seeing a shocking scene before ejecting from the aircraft: multiple Iranian drones hovering in the air, moving in a unified formation resembling a jellyfish. This has sparked a heated debate within U.S. intelligence circles that has yet to subside. If the pilot indeed saw what he described—a coordinated moving formation—it would mark a stunning leap in Iran's drone capabilities. Sources said the pilot described the Iranian drones as interconnected, moving as a single entity, with "smaller drones positioned like legs beneath larger ones, as if engineered by aliens."
