Abstract
One major effect of the covid pandemic was, that it has not been easy to travel in the last two years. Many airlines have had to report losses. Despite massive state aid, they have had to reduce their fleet and personnel as well. There were also fewer new airplanes ordered. In our article, we would like to give a brief overview of the aviation industry, which is one of the most technology intensive sectors. These factors make this branch a global oligopoly, as there are few companies producing civilian and/or military aircraft on the market. The race for the conquest of space is huge. American spacecraft landed on Mars, Chinese spacecraft collected rock samples on the Moon. Airbus SE and the Boeing Company, these two largest aircraft manufacturers have joined the aerospace industry too, building bigger and bigger part on the research, developing new technologies.
