This chapter examines the legal framework governing drones and liability in the event of collisions and damage to third parties on the surface. With the increasing use of unmanned aircraft systems (UAS) for commercial, recreational, and governmental purposes, the legal landscape has evolved to address issues related to responsibility and compensation. The chapter explores the principles of liability under international, European, and national regulations, analysing the applicability of strict liability versus fault-based liability in drone-related incidents. Special attention is given to the role of airworthiness requirements, operational rules, and insurance obligations in mitigating risks. The chapter concludes by evaluating potential legislative reforms and technological solutions aimed at enhancing safety and ensuring effective compensation mechanisms for affected parties.
