destroyed-and-abandoned: This Sherman Tank was stranded on the reef during the invasion of the island of Saipan during WWII. Its turret is still frozen in time, taking aim at a Japanese gun emplacement on the beach.
A destroyed WWII plane, 1944 and recent. I have my doubts on this one, sixty plus years of salt water and oxygen exposure, pacific typhoons and armchair-level explorers? A location added would've helped the skeptic in me quiet a bit.
