It turns out that the parts they saw fall out of the sky were from their best Iranian Zelzal missile (reportedly 200 km range). Israeli planes struck a truck carrying these missiles en route to a genocidal attempt by Hizbollah to mass murder Jews, perhaps in Tel Aviv.
As a result of the bombing, one of the missiles flew up in the air and then came crashing down again - and that was what the Arabs saw.
Of course, a Syrian commenter on the Jerusalem Post article linked to above is certain that Hezbollah really did shoot down an IAF plane - with a Katyusha. Showing once again the amazing ability of Arabs to disregard facts when they interfere with their own fantasies.
