It is significant that the morse code sign for "V" is figuring so prominently in the Victory Campaign. When the full history of this war is written, it will be revealed that the assistance of radio and aviation has been vital. It is fairly obvious that the Victory Campaign has been nicely timed, as we are undoubtedly around the corner now, and victorious peace may be with us again at any day now. Let us hope that the two sciences will never again have the restrictions of officialdom which have hampered their progress in the past. Let us hope that the rising generation will be afforded every assistance to enjoy both radio and aviation as scientific hobbies. Never let us forget that "The Price of Peace Is Eternal Vigilance."
