The jurisdictional issues raised in this chapter are both technical and of current academic interest. For instance, it may be asked: what is meant by “international space”? Which laws should govern the airspace of international spaces? Should it be the laws governing the specific international space in question or should it be the general principles of air law? Furthermore, there is the classic debate in academic literature as to whether the airspace above the high seas is also part of the common heritage of mankind.
