I think it deserves an own thread since Launches, Re-entries - regular or mishaps will interact with air traffic even more in near future.
The outlet SpaceNews has given an (US/MIL) ATC expert (Matthew Lewallen) some room to present his proposal for future close interoperability of space traffic and air traffic. A very good thought in my view.
