An aircraft crash can occur due to environmental effects, technical issues, or human error. On October 20th, 2014, an Unijet plane crashed in Russia, resulting in 4 fatalities. Key crash protection systems include parachutes to guide planes without power or control, two-stage airbags for land or water crash landings, and detachable wings and fuel tanks to reduce fire and explosion risks. Air traffic safety can be improved by securing a safer operational and traffic environment, ensuring aircraft safety, enhancing emergency services, and increasing research and development.
