The monograph addresses the topic of modern forms of air transport, which are becoming more and more popular due to their efficiency and potentially lower costs. Discusses the benefits and challenges of uncrewed cargo and passenger transport as well as single-pilot flights, focusing on technological, operational, safety and social aspects. The safety of transporting passengers and cargo in unmanned and single-pilot aircraft is a topic that arouses many discussions and analyses. These innovations aim to increase efficiency and reduce operating costs, while maintaining or improving safety levels. In the context of unmanned cargo transport, this form of transport is perceived as less risky because it eliminates the threat to human life in the event of a failure. Unmanned trucking can serve routes that are too costly or unprofitable for traditional airlines, increasing the availability and frequency of deliveries. However, the reliability of systems and the ability to independently respond to failures are crucial to ensure safe and on-time deliveries. Unmanned passenger transportation has the potential to reduce human error, which could improve travel safety. Automation of on-board processes could contribute to a uniform level of safety. However, the need for strong redundancy systems and gaining public trust pose significant challenges. Information and education campaigns can help eliminate fears associated with new technology. Single-person flight crews, especially in cargo operations, can bring significant savings. In passenger transport, they are an intermediate step between traditional crews and fully autonomous flights. However, single-person crews require a high level of training and advanced systems to support the pilot in emergency situations. Safety aspects are crucial when introducing new aviation technologies. Systems must be reliable and equipped with advanced monitoring and control mechanisms to respond to unforeseen events in real time. Air traffic management must be reorganized to accommodate unmanned aircraft. Cybersecurity plays an important role because the complexity of aviation systems makes them vulnerable to attacks. It is necessary to use data encryption, authentication mechanisms and attack detection systems to ensure the reliability and integrity of systems. Regulations and standards must evolve to meet the challenges associated with unmanned and single-person aircraft systems. The development of detailed test scenarios and certification processes is essential, as is cooperation between regulatory authorities, manufacturers and operators. Training ground crews, air traffic controllers and pilots is crucial for effective cooperation with advanced automatic systems. Investment in intensive training programs is essential to ensure safe and effective flight operations. Technological aspects such as automation, artificial intelligence, air traffic management and cybersecurity play a key role in the development of aviation. Innovation in these areas is essential to ensuring safe and efficient aviation operations. Social aspects, including public acceptance, are important for the success of pilotless transportation. Building trust by educating the public and demonstrating the effectiveness of systems is key to introducing new aviation technologies.

This exhaustive work in several volumes and over 2500 pages provides a thorough treatment of ultra-high temperature materials (with melting points around or over 2500 °C). The first volume focuses on carbon (graphene/graphite) and refractory metals (W, Re, Os, Ta, Mo, Nb and Ir), whilst the second and third are dedicated to refractory transition metal 4-5 groups carbides. Topics included are physical (structural, thermal, electro-magnetic, optical, mechanical, nuclear) and chemical (more than 3000 binary, ternary and multi-component systems, including those used for materials design, data on solid-state diffusion, wettability, interaction with various elements and compounds in solid and liquid states, gases and chemicals in aqueous solutions) properties of these materials. It will be of interest to researchers, engineers, postgraduate, graduate and undergraduate students alike. The readers/users are provided with the full qualitative and quantitative assessment, whichis based on the latest updates in the field of fundamental physics and chemistry, nanotechnology, materials science, design and engineering.
