luftfartrumfart

Luftfartrumfart is a coined term that merges the Swedish words luftfart (air travel) and rymdfart (space travel) to denote an integrated concept of transportation that spans from the Earth's atmosphere into outer space. In speculative or futurist discourse, luftfartrumfart refers to the envisioned regime, technology, and infrastructure required to manage vehicles, operations, and safety across the boundary between aviation and astronautics, aiming for seamless transitions and coordinated traffic between airspace and orbital domains.

The concept covers vehicle design considerations, propulsion and life-support systems capable of operating in both atmospheric and vacuum conditions, as well as navigation, guidance, and control architectures that can handle multi-domain flight envelopes. It also includes ideas for unified traffic management, shared corridors for air and space activities, and the development of spaceports that function as extensions of traditional aerodromes.

Regulatory and governance aspects are central to luftfartrumfart. Today, civil aviation is governed by international and national aviation authorities under ICAO, while space activity is governed by space law at the UN level and national space agencies. A practical luftfartrumfart regime would require new cross-domain standards, safety certifications, and liability frameworks to address risks such as mid-flight anomalies, airspace and orbital deconfliction, and space debris.

The term is not widely adopted in official policy and is mainly found in speculative literature and academic discussions about space traffic management and future aviation concepts. See also: space traffic management, air traffic management, spaceport, aviation, space law.
