I'm happy to share with you my Bachelor's Thesis Project: "Aviation Security as Public Policy and its transformation since 9/11 attack"
Study of aviation security as public policy in Europe and United States prior and after 9/11 attacks. Through deep analysis of all the components of security provision, making special attention on financial part, the thesis goal is to find the best public/private equilibrium that ensures effective safeguarding of aviation without impacting negatively on air industry development through excessive economic burden.
