9. Amelia Earhart – Disappeared While Flying Across The Globe
Perhaps the most famous celebrity disappearance, Earhard’s fame was more historical than most on this list. As many learned in grade school, Earhart was the first female to pilot an aircraft across the Atlantic Ocean. She attempted to one-up herself and become the first female to circumnavigate the globe, but mysteriously vanished during her efforts.
It isn’t hard to apply Occam’s Razor and give an educated guess at what happened, and many have: her plane crashed somewhere over the Pacific Ocean. However, search efforts lasted several years, and still neither a body nor any evidence of her plane could be found. The world may never have a full answer to her mystery, but her husband George P. Putnam eventually called off his search, officially declaring her “presumed dead” in 1939.
