Re: Back to that drone. On BBC Iran says it electronically hijacked and landed it.
Isn't that always the case? Both belligerents are perfectly aware of what the other is up to. It's their people who have to be shielded from the truth.
There is one clue in this mystery. Iran is a huge country, much of it covered with inaccessible mountainous or desert terrain. It is highly unlikely the drone just fell out of the sky and they stumbled on to it.
