There was an article not long ago about Iran testing drones. I think that answers the UFO sightings.
Iran supplied those drones to the Hezbullah so i'm sure they've got their own.
Not necessarily at all. In fact, you are probably quite wrong.
There has been a long history of reliable professional military pilots etc. sightings of authentic appearing UFO's of typical UFO craft shapes and sizes in Iran dating AT LEAST as far back as the Shah.
I'm sure the information is readily available.
