Global catastrophic risk <=SEP=> A global catastrophic risk is a hypothetical future event that has the potential to damage human well-being on a global scale . Some events could cripple or destroy modern civilization . Any event that could cause human extinction is known as an existential risk .   Potential global catastrophic risks include anthropogenic risks ( technology risks , governance risks ) and natural or external risks . Examples of technology risks are hostile artificial intelligence , biotechnology risks , or nanotechnology weapons . Insufficient global governance creates risks in the social and political domain ( potentially leading to a global war with or without a nuclear holocaust , bioterrorism using genetically modified organisms , cyberterrorism destroying critical infrastructures like the electrical grid , or the failure to manage a natural pandemic ) as well as problems and risks in the domain of earth system governance ( with risks resulting from global warming , environmental degradation , mineral resource exhaustion , fossil energy exhaustion , or famine as a result of non-equitable resource distribution , human overpopulation , crop failures and non-sustainable agriculture ) . Examples for non-anthropogenic risks are an asteroid impact event , a supervolcanic eruption , a lethal gamma-ray burst , a geomagnetic storm destroying all electronic equipment , natural long-term climate change , or extraterrestrial life impacting life on Earth .

Boeing <=SEP=> The Boeing Company ( -LSB- ˈboʊ.ɪŋ -RSB- ) is an American multinational corporation that designs , manufactures , and sells airplanes , rotorcraft , rockets , and satellites worldwide .

Airplane <=SEP=> An airplane or aeroplane ( informally plane ) is a powered , fixed-wing aircraft that is propelled forward by thrust from a jet engine or propeller . Airplanes come in a variety of sizes , shapes , and wing configurations . The broad spectrum of uses for airplanes includes recreation , transportation of goods and people , military , and research . Commercial aviation is a massive industry involving the flying of tens of thousands of passengers daily on airliners . Most airplanes are flown by a pilot on board the aircraft , but some are designed to be remotely or computer-controlled .   The Wright brothers invented and flew the first airplane in 1903 , recognized as `` the first sustained and controlled heavier-than-air powered flight '' . They built on the works of George Cayley dating from 1799 , when he set forth the concept of the modern airplane ( and later built and flew models and successful passenger-carrying gliders ) . Between 1867 and 1896 , the German pioneer of human aviation Otto Lilienthal also studied heavier-than-air flight . Following its limited use in World War I , aircraft technology continued to develop . Airplanes had a presence in all the major battles of World War II . The first jet aircraft was the German Heinkel He 178 in 1939 . The first jet airliner , the de Havilland Comet , was introduced in 1952 . The Boeing 707 , the first widely successful commercial jet , was in commercial service for more than 50 years , from 1958 to at least 2013 .
