World War II came to an end 70 years ago this summer. In August 1945, the conflict left 73,515 U.S. soldiers missing. Ever since, the U.S. military has chipped away at that last number. More recently, they’ve received a little help from underwater robots, reports Peter Rowe of The San Diego Union Tribune. Scientists at the Scripps Institution of Oceanography at UC San Diego, the University of Delaware and other institutions have teamed up with military historians to find the final resting places of the WWII missing in action. The project is called BentProp. It’s been around since 1993, explains Rowe. So far, BentProp divers and historians have recovered eight soldiers’ remains with many more waiting to be authenticated. While mapping and studying coral reefs around the islands of Palau in the South Pacific, Scripps oceanographers Eric Terrell and Mark Moline ran into BentProp volunteer divers.
