First Sea Lord Winston Churchill establishes the policy for the air defense of the United Kingdom. He calls for the use of antiaircraft artillery and searchlights around likely targets; the deployment of aircraft forward in Europe to attack all Zeppelin and other enemy air bases within reach; the interception of enemy aircraft between Dover and London by British aircraft, coordinated by telephone and telegraph; the basing of aircraft at Hendon specifically for the defense of London, with their crews specifically trained and equipped for night-fighting and their operations also coordinated by telephone; a blackout in major cities; and warning the public of the dangers of air attack, precautions against it, and how to take shelter when under air attack
