You are probably talking about this:
-June 8, 1982- The Peace For Galilee operation (The Lebanon War): The destruction of the entire Soviet-Syrian air-defense system in Lebanon within few hours without a single warplane lost- Syria with the Soviet Union built up an overlapping network of SAMs, and the density of SAM site locations was unmatched anywhere in the world including the Soviet Union itself.
Also the IAF achieved a number of 100 Syrian planes shoot-downs, 88 of them in dogfights, without a single Israeli plane being shot down in dogfights.
The IAF proved that it has learned from the mistakes of the Yom Kippur War and proved once again that it is master of the skies.
Yep. God, how I cheered when I heard about that!
