I think this is probably the most plausible explanation. Apparently six weeks ago the Iranians took delivery of the Russian's latest Avtobaza ground-based electronic intelligence and jamming system. http://www.flightglobal.com/blogs/the-dewline/2011/12/avtobaza-irans-weapon-in-rq-17.html http://www.flightglobal.com/blogs/the-dewline/2011/12/avtoba... If that's the case it's a win win for both Iran and Russia. Iranians get the press coup of poking the US's eye whilst Russia walks away with an RQ-170 (to reverse engineer and resell to the Iranians of course).
