¡@¡@Mankind has always had an interest in the unknown. Whether it is unidentified flying objects3, little green men, or mysterious disappearances, people have looked up to the night sky in wonder. National Geographic Channel's new show, Invasion Earth, attempts to solve these mysteries.
¡@¡@In 1978, a young pilot named Frederick Valentich was flying a small propeller aircraft across the Bass Strait in Australia. It was a routine flight until something very strange happened. Valentich reported to air traffic control in Melbourne that a series of small flashing lights traveling at high speeds were circling around his aircraft. Despite Valentich's report, the control tower in Melbourne could see no such objects on their radar4 screen. Moments later, communication between Valentich and air traffic control was cut off. Neither Valentich nor his aircraft was ever seen again, and the reported event surrounding the flashing lights remains a mystery to this very day. Was it an alien abduction5 or just pilot error that caused Valentich's plane to go missing? Invasion Earth circles the globe to explore unexplainable mysteries just like this one. Tune in this month and see if the truth is really out there.
