Europe's vulnerable airports

The targets of the European terror plot which has been subject of travel advisories this week apparently included the crowded check-in areas of five major airports:

A law enforcement official told ABC News that terror teams could have staged commando-style attacks on pre-security areas packed with travellers before they boarded flights.

Which is why, in Ben-Gurion airport, passengers have been through several layers of security before they even get close to the check-in desk: on the road approaching the airport; as they move towards the airport doors; and at the entrance. In Israel, essentially, no area of the airport is 'pre-security'.
