ObjectivesThe study was to analyze the concept of Responsive Space Systems alternative launch and set of the nanomicro satellites into Low Earth Orbit. The analysis focused on aircraft-rocket space systems, where platform for launching a rocket with a satellite is an aircraft.The aircraft in the role of the platform provides opportunities, system thus the operator doesn't need bases or space ports in European conditions.MethodsAnalysis of the research area, focused on the review, critical analysis, evaluation of the available literature, resources. The work was supplemented with the results and recommendation of the research project recently carried out at the MUT.ResultsSystems were presented in view of the war in Ukraine. Existing operational and currently designed systems were reviewed. Article evaluated the aerial-rocket systems for launching objects into the LEO in the context of the system's operational costs and capabilities, potential market and further military and civilian applications also the needs of the Polish Armed Forces. Combat aircraft and rocket kits based on decommissioned from PAF fighters were proposed and valuated.ConclusionsImplementation of system gives autonomy from countries or companies offering space services, possibility of mastering new capabilities of placing satellite systems for security&defense purposes. For the PAF, aircraft-rocket kits based on phased-out supersonic combat aircraft may be the start of the development and construction of the national Responsive Space System. The country's scientific-industrial base has competence to design&build such a system. Polish Space Agency can act as an integrator of the system just as NASA did in the 1960s.

ObjectivesThe purpose of this article is to present the impact of the Covid-19 pandemic on the operation of airlines and the aviation sector as a whole. The pandemic forced airlines to make many changes in their operations and greatly affected the entire aviation sector. The operation of the aviation sector during the pandemic period was affected by the administrative closure of flights for months, as well as the regulation banning flights to selected countries.MethodsThe study used the method of analyzing statistical data and reports on the aviation sector. The method of analyzing statistical data made it possible to compare data from the aviation sector on, among other things, the number of passengers carried, and the number of flights made.ResultsAs a result of the development of the Covid-19 pandemic, the aviation sector reduced the number of flights operated, which contributed to a decline in the number of passengers carried and heavy losses for the sector. During the pandemic period, the growth of airlines was sharply halted.ConclusionsAviation around the world operated for several months in a completely new and highly unpredictable reality. The crisis caused by the Covid-19 pandemic is the biggest crisis in aviation history. The sector needs to define clear rules and messages in crisis situations.
