Re: iranian plane "crash"
That little missile was fired near an airport because that was a little man fired heat seeker and that's the only place airliners are in range.Yes. there are markers on the plane.
Also, the plane was flying away, not towards to the airport so not a threat.
However, the Russian Missile launchers are computerized, not manned by a human all the time. Computers can make a mistake if the launcher is set on a highten alert status.
Russian-made SA15 missile
