Five German Navy Zeppelins attempt to bomb London after a five-week hiatus, L 15 bombs central London, during which RFC pilot John Slessor, flying a BE-2c, intercepts her, becoming the first man to intercept an enemy aircraft over the United Kingdom, although he is unable to fire. The other four Zeppelins scatter their bombs over various towns and the countryside. The raid is one of the deadliest of World War I, killing 71 people and injuring 128.
