1997 Israeli helicopter disaster

The 1997 Israeli helicopter disaster occurred on 4 February 1997. 73 Israel Defense Forces soldiers were killed when two Sikorsky S-65C-3 Yas'ur 2000 helicopters, 357 and 903, collided over She'ar Yashuv in northern Israel. The helicopters were supposed to have crossed the border into Israel's "security zone" in Lebanon, but were hovering while waiting for official clearance to go. Previously Israel had moved troops by ground, but this policy was changed as the threat of roadside bombs from Hezbollah increased.
