  In an era marked by unprecedented climatic upheavals and evolving urban
landscapes, the role of advanced communication networks in disaster prevention
and management is becoming increasingly critical. This paper explores the
transformative potential of 3D wireless networks, an innovative amalgamation of
terrestrial, aerial, and satellite technologies, in enhancing disaster response
mechanisms. We delve into a myriad of use cases, ranging from large facility
evacuations to wildfire management, underscoring the versatility of these
networks in ensuring timely communication, real-time situational awareness, and
efficient resource allocation during crises. We also present an overview of
cutting-edge prototypes, highlighting the practical feasibility and operational
efficacy of 3D wireless networks in real-world scenarios. Simultaneously, we
acknowledge the challenges posed by aspects such as cybersecurity, cross-border
coordination, and physical layer technological hurdles, and propose future
directions for research and development in this domain.
