The Battle of L.A. UFO Incident

In February 1942 the military opened fire on an object that flew over Los Angeles. The incident is referred to as the Battle of Los Angeles and is best-known by the iconic image of searchlights converging on an object while explosions from anti-aircraft fire erupt nearby. Researcher David Marler has researched this case, and when he puts together all of the facts, media stories from the time and government documents on the incident, it is more mysterious than ever. In this lecture, David shares with us what he found and why this case remains unsolved.
