ABSTRACT
One of the stranger things about space law is that when or where that legal regime applies is not yet settled. There is no specific international agreement as to any boundary between air-space and outer space.1 The Outer Space Treaty of 1967 and its companions are silent on the matter. In the future the regimes of ‘space’ and ‘air-space’ may well be delineated similarly to the distinction that is made between the high seas and other areas of the sea subject to national sovereignty,2 but as we write there is uncertainty – not that space law exists, but as to the exact location of its application. Needless to say there have been many suggestions.
