Lord Ellenborough in Pickering c Rudd (1815) 4 Camp 216 said it would not be a trespass to pass over a man's land in a balloon. Lord Wilberforce in Commissioner for Railways v Valuer-General[1974] AC 328, at 351 said that it was unlikely that such a sweeping, unscientific and unpractical doctrine as that 'land' meant the whole of the space from the centre of the earth to the heavens would appeal to the common law mind. If the latin maxim were applied literally it would lead to the absurdity of trespass being committed every time a satellite passed over a suburban garden. The problem in this case was to balance the rights of a landowner to enjoy the use of his land against the rights of the general public to take advantage of all that science now offered in the use of airspace. The best way to strike that balance in our present society was to restrict the rights of an owner in the airspace above his land to such height as was necessary for the ordinary use and enjoyment of his land and the structures upon it, and to declare that above that height he had no greater rights in the airspace than any other member of the public.
