Bombing from Aircraft

The intense air activity in Europe has aroused a keen interest in the various methods of bombing which can be employed. But anything written on this subject in time of war needs to avoid the risk of disclosure of matters which must be kept confidential so long as hostilities last. Hence a full discussion on the subject is not possible. The British and German methods differ, as might be expected, in many important respects, though the fundamental principles employed must necessarily be the same, since the laws of Nature do not alter with political boundaries.
