French aviation security at airport Roissy Charles de Gaulle, the air plane inspectors of the General Directorate of Civil Aviation control air crafts - their appearance on the tarmac just minutes from take-off is a nightmare for pilots and mechanics. 35 year-old Nesrine is the only female technical controller at the airport of Roissy-Charles de Gaulle - she can prevent an aircraft from taking off and force its passengers to exit the plane if she detects a security breach. She inspects about two air crafts per day. Every minute of delay can cost up to 1,500 euro to the company. In 2012, 2,442 flights of foreign airline companies have been inspected. 673 of them were delayed before taking off because of security problems. Three planes needed so much maintenance that they were forbidden from taking off.
