UAVs have become a critical component of U.S. military operations, reducing the need to risk the life of a pilot, while performing tasks considered dull, dirty, and dangerous. UAVs currently are serving an important intelligence, surveillance, search, and destroy function in Operation Enduring Freedom. Since September 11, 2001, the public has increasingly been made aware of the role that military UAVs, such as the Predator and Global Hawk, play.

If aeroplanes and passengers, as well as property and people on the ground are to be protected, potential perpetrators of aviation terrorism must be prevented from breaching security checkpoints and gaining access to ‘secure’ airport areas and to aircrafts. Given the interconnectedness of the air transportation system, a sufficiently high level of security must be provided throughout the entire system. In this chapter we examine terrorism issues relevant to airline and airport security internationally, a topic that has received much attention since 9/11. Understanding the key issues is crucial in evaluating the various methods of regulating and providing aviation safety and security. The purpose of this chapter is to review the key features of the Aviation and Transportation Security Act and the characteristics of the resulting security policy. Then we examine terrorism, previous terrorists' acts against aviation as well as current and future aviation threats. A summary of our major points completes the chapter.

The global COVID-19 pandemic highlighted the interconnectivity and interdependence of the modern world economy and international society’s epidemiological vulnerability to the global transmission of human infectious diseases by air travel. The rapid formulation of new pandemic policy responses for the air transport industry at both a national and international level revealed complex tensions between mandatory ‘stay-at-home’ public health interventions and international travel restrictions, which were designed to limit the virus’s spread but which dramatically disrupted everyday social activities, and political and economic imperatives to reopen global air travel as quickly as possible. The aim of this chapter is to examine the development of global policies for the air transport industry from the perspective of aviation public health policy, airline passengers, air freight and financial support for airline and airport operators.

On December 24, 1989, an armed insurrection began in Liberia. Charles Taylor, a former government official, led a rebel force, the National Patriotic Front of Liberia (NPFL), into the north-eastern Nimba County. A breakaway faction, the Independent National Patriotic Front (INPFL), led by Prince Yormie Johnson gained control of central Monrovia – the capital – and killed the President Samuel Doe. The Economic Community of West African States (ECOWAS) intervened in August 1990, sending monitoring troops (the ECOWAS Military Observer Group, ECOMOG), and convened a national conference which elected an Interim Government of National Unity. In October 1990, ECOMOG established a neutral zone in Monrovia where Dr. Amos Sawyer was installed as Interim President in November. Various different factions and opposition groups were formed and clashes between the rebel groups and the Liberian army continued.
