Amelia Earhart disappeared in July of 1937 but not until now has there been footage of her preparing for her final flight.

In anticipation of "Amelia Earhart's Last Photo Shoot," an 80-page e-book written by Nicole Swinford, a video of Earhart at what is believed to be Burbank Airport (now named Bob Hope Airport) posing for pictures has been released, according to The Washington Post. 

While Swinford believes it shows Earhart at Bob Hope Airport in May of 1937, some believe the footage is actually from two months earlier, in March of 1937," CNN reports.  Similarly, the identity of the cameraman is not exactly clear.

"The black-and-white, 16mm film was apparently shot as Earhart posed for her last photo shoot just before the famed aviator attempted to circumnavigate the globe. The cameraman appears to be John Bresnik, the brother of Earhart's personal photographer, Al Bresnik," The Washington Post reported. However, the CNN report says "The shooter of the film footage remains unknown."

The video was discovered by John Bresnik's son, John, who inherited it after his father's 1992 death.

"It just always sat it in a plain box on a shelf in his office, and on the outside it said, Amelia Earhart, Burbank Airport, 1937," Bresnik told The Associated Press.

Earhart and her navigator Fred Noonan famously disappeared after she attempted to become the first female pilot to fly around the world. Their last known location is somewhere between New Guniea, which the pair departed from on July 2, and Howland Island, "a tiny speck of land in the Pacific, midway between Australia and Hawaii," according to the AP.  

Information on Earhart, especially regarding her final public appearances, has always been hard to come by and full of mystery, but experts do believe this newly discovered video is authentic.
