Successful aviation has evoked some peculiar things
in the way of legal action and interpretation of the law.
It is well understood that a man's property cannot
be used without his consent. This is an old established
principle in common law which holds good today.
The limits of a man's property lines, however, have
not been so well understood by laymen. According to
eminent legal authorities such as Blackstone, Littleton
and Coke, the "fathers of the law," the owner of realty
also holds title above and below the surface, and this
theory is generally accepted without question by the
courts.
