While I was actively traveling to Zürich (for three years before Covid pandemic), I noticed that the Israeli airplane is always being followed by an armored police car with a machine gun turret on top. The car moves parallel with the plane all the way during taxiing.
As far as I could notice, no other planes/companies had this security measurement. Does anyone know why is this happening? Are there some increased security risks connected to the planes/passengers coming to/from Israel?
