The monograph discusses the problem of aerial terrorism, one of the biggest challenges humanity faces in the 21st century. Its main goal is to answer the question of whether international legal regulations serve as an effective tool in the fight against terrorists who target civil aviation. The book itself is divided into three chapters: the first one focuses on the theoretical aspect by describing the term “aerial terrorism” itself from a legal perspective. The second one is an in-depth overview of key legal instruments drafted under the auspices of ICAO, the United Nations, and the European Union, that together form a juridical core for the fight against air terrorists. Finally, the third is a case study that depicts how the mechanisms described in the previous parts function in practice.
