Abstract - Air travel has changed global transportation in the last century. It allows the quick movement of people and goods and helps build economic and cultural connections across continents. Despite ongoing improvements in aerospace engineering, aircraft design, and strict regulations, aviation accidents, while rare, are still a serious public safety issue due to the potential for large losses of life. According to the International Civil Aviation Organization (ICAO), the worldwide scheduled air transport fatal accident rate was about 1.11 per million departures in 2022. Every year, hundreds of fatalities occur, mainly due to high-impact crashes, post-crash fires, toxic smoke inhalation, and major structural failures. Traditional aircraft safety systems have primarily focused on protecting the aircraft itself rather than the individual passenger. Current in-flight protection methods mainly include lap seatbelts, drop-down oxygen masks, and manual crew evacuation instructions. These measures leave passengers very exposed to various threats in the critical moments after an impact.To fill this urgent gap in aviation safety, this paper proposes designing and prototyping the "SkyPod," an autonomous, deployable protective capsule system that integrates into current commercial aircraft seating. The SkyPod acts as a separate, modular protective unit that absorbs crash impact energy, protects passengers from deadly fire and smoke, and offers buoyancy during emergency water landings. The proposed system uses a multi-sensor array that includes MPU-6050 6-axis accelerometers and gyroscopes along with BMP280 barometric pressure sensors. This combination involves real-time data processing to detect upcoming crash events. When a crash trajectory is confirmed, the system's microcontroller activates a fast inflation mechanism using compressed CO2 cartridges. In less than two seconds, the system surrounds the passenger with a rigid, thermally insulated, fire-resistant shell made from Nomex and Kevlar laminates. This capsule absorbs and redistributes kinetic energy through honeycomb structures and elastomer dampers, blocks dangerous cabin debris, and ensures breathable air using integrated HEPA and activated carbon filters. This review outlines the design framework, hardware and software requirements, practical engineering applications, testing methods, and future trends needed to shift passenger safety from a reactive evacuation mindset to proactive, intelligent encapsulation.
