I B/lark f Defense While we build up the military to meet any challenge, let us remember that no nation is stronger than its communications. With peaceful Douglas wings over the Americas our airlines have per. fected the fastest, most efficient system of scheduled communications the world has ever known. Because this system is integrated with and best serves the economy we must defend, it should be accelerated in time of emergency. Only through expansion can this bulwark of defense be improved.
