How to keep airplanes and restaurants in our civilization

I had never imagined that a pandemic like corona would someday sweep away our civilization.

What I miss most is the airplanes and the restaurants which always brought encounterings with foreign countries and other people.

Constant disinfection of such closed spaces will save them.
I propose to explore the possibility to use either of ion discharge, ultra-violet lamp etc. for constant disinfection of the closed spaces.

Some of them are harmful to human beings, so a thorough and quick study should be made.
