It would be ironic if the only thing found through the search and rescue efforts was her plane.
Part of the Earhart investigation focused on how she was to switch between radio beacon and a some other signal (like morse-code??) on the half-hour as a navigation aid. But at that time, everyone used a different time zone. A ship from Hawaii was anchored off the island (Howland?), and was 2.5 hours off from the island! (The ship was still on Hawaii time.)
Anyway - the result was using Mean Greenwich Time for all travel after that.
I imagine some changes will be coming as a result of this flight getting lost.
