Human spaceflights will extend regulatory and legal framework governing civil aviation

Sub orbital flights offer an important approach to the evolution of the market and demonstrate the safety of space flights and the profitability of space tourism. By contrast, aviation is a global industry, largely commercial, involving the range of activities from engineering design to marketing. Aviation has very high safety levels developed over decades of experience carrying billions of passengers (Sietzen, 2002). This paper will consider briefly the expansion of the airspace system concept to include commercial space operations as an integral component, highlighting legal concepts learned in the frame of the modernization of the civil aviation regime and of the outer space law, the so-called "Corpus juris spatialis internationalis" (Reijnen, 1994). At present, comparison of aircraft and spaceplane legal regimes shows that the problems of the spaceplane, even only the legal ones, are not easily solved
