New Uses of the Protozone

  • Joseph N. Pelton
Part of the Springer Praxis Books book series (PRAXIS)


There is an interesting book by David Loth entitled How High Is Up that explored the problem that has been an issue for national armed forces seeking to defend their countries for many centuries. The conclusion in Loth’s book is that despite efforts to define things like national air space and sovereignty over land of a particular country, the practical answer has been the area that can be effectively defended. Today, national commercial air space is generally accepted to rise up to 20 kilometers (12.5 miles).
