In the 80 years since Amelia Earhart and her navigator vanished while flying over the Pacific on July 2, 1937, people have desperately tried to figure out what really happened to the famous aviator. Given new developments, such as an intriguing photograph featured in "Amelia Earhart: The Lost Evidence," a History investigative special that will air on Sunday, July 9th, it's a good time to look at Earhart's last flight, the factors that may have contributed to what went wrong and the current prevailing theories about her disappearance. Unlike Manning, neither Earhart nor Noonan were adept at wireless code. This prompted Earhart to get rid of the CW (telegraph code key) transmitter on her plane, as she felt it would be "dead weight" with just her and Noonan onboard. Before departing, she also dropped a trailing antenna that would have allowed her to use the 500-kilocycle marine frequency; instead of Morse code, Earhart planned to communicate by voice at higher bandwidths.
