The attack on in El Al flight by rocket propelled grenades last December in Geneva, Switzerland was foiled by Swiss and French intelligence divisions. The attack was to be carried out by Islamic Extremists.
The Yedioth Aharonot newspaper reported that a secret agent working undercover amongst an Islamic terror cell in the city discovered the plan after three immigrants of Arabic origin boasted of their attempts to smuggle weapons from Russia with the ultimate goal of shooting down an Israeli plane at the airport.
When the matter was reported to Israeli security, El Al changed the flight paths of all its Geneva-bound planes, landing them at Zurich Airport the following week.
Swiss officials reported that no arrests were made following the discovery since the plan had yet to reach its final operational stages.
El Al has reportedly installed the Flight Guard Self Protection System at a cost of one million dollars per plane on some of its fleet, and plans to install it in all its jets in the future. via the Jerusalem Post
