On a warm summer night in July of 1999, John F. Kennedy, Jr., his wife and her sister took off from a small New Jersey airport in his private plane. But as the trio made their way to Martha's Vineyard for a brief stopover, tragedy struck. At about 9:41 that evening, Kennedy's plane disappeared from radar and plunged into the Atlantic Ocean. Is it possible that Kennedy became disoriented and literally flew his plane into the ocean? Or has the U.S. Coast Guard uncovered evidence that would contradict that finding? And in Part Two of this episode we'll examine a world abounding with life... life of which humans are only a small part. Humans are convinced they are at the top of the heap - but are they? Birds, bees, bats, and even fish appear to have a sixth sense that far surpasses the limits of human sensory perception. Examples are startling. Is it possible that humans have the same abilities but have forgotten how to use them? New research techniques may help us find the answer.
