From the Introduction: "Congress has encouraged the growth of commercial space activities by requiring federal agencies to use private launch services and establishing offices to oversee commercial activity. In 2018, 35 commercially licensed launch and reentry events occurred at U.S. spaceports, a 100% increase from the 2016 level. Some forecasts project a rapid increase in demand for commercial launch services in coming years. The growth in launch activity has been accompanied by a rise in the number of commercial launch providers and locations--spaceports--licensed for launch services. Expanded commercial space activity has brought increasing attention to the use of U.S. airspace. Interest groups representing airlines and general aviation have voiced concerns about more frequent restrictions of airspace to accommodate commercial launch events. The Federal Aviation Administration (FAA), which controls the use of the national airspace, has been challenged to accommodate the needs of commercial space launch operators and their clients while at the same time ensuring the safety of traditional aircraft operations, which it predicts will also grow."
