Spaceplanes - Space Traffic Management and Space Port Management in Europe

, 2018
Spaceplanes - aircraft that reach their destination on Earth through space - are a conceivable addition to future aviation. They will fly through airspace and land at airports. Operational scenarios are already now being investigated and evaluated in Germany and elsewhere in Europe, including the identification of possible landing sites (spaceports).
