UFOs Declassified

Just a few months after Japan's bombing of Pearl Harbor, Los Angeles came under an air attack of its own, but from who, or what, remains a hotly debated topic. Some people, including a former FBI agent and UFO investigator, believe it may be the first and best-documented case of an extraterrestrial visitation. Others are more skeptical. One thing is certain. Something incredible happened on February 25, 1942. Now, with recently declassified top-secret documents and startling new evidence, we attempt to unlock this 73-year-old mystery.

Each year, there are millions of commercial flights around the world, and thousands of aircraft in the sky at any given moment. With that many eyes in the skies, it's little wonder that some of the most stunning UFO sightings have been reported by airline pilots. Relive three of the most riveting encounters, which took place over Alaska, New Mexico, and the English Channel. Join us as we open up recently declassified government files and talk to eyewitnesses in an attempt to explain the seemingly unexplainable.
