Igal Ish-Tov points to this, which says that a ground-to-air missile was fired at an El Al flight on route from Tel Aviv to Moscow and missed. There's no confirmation of this anywhere that I can see.

Update: Ynet has it. Israeli Foreign Ministry has confirmed the incident and says that the missile was probably fired as part of a military exercise. A Siberian Air plane was accidentally shot down lost Oct in the Ukraine. This incident was apparently in Belarus.

In the report I blogged earlier about the LAX shooting, Army Radio was apparently taken by the prank (Thanks to Ken Layne for pointing it out).
