I don't see the Israelis being interested in tipping their hand to any extent over their ability to penetrate Persian air defenses, so the aircraft blurb I think is factually wrong but I can see Mossad wanting that inserted into the story if for no other reason than to have the Iranians question it and perhpas chase phantoms and reveal weaknesses in the process. The later would mean human assets on the ground, but I think there are several of those in-country already, so it seems like a possible scenario to me.
