After more than half a century at the bottom of the Atlantic Ocean, a World War II-era aircraft carrier potentially containing one hundred barrels of nuclear waste has been rediscovered by scientists.

The United States National Oceanic and Atmospheric Administration said Thursday that it has once again located the USS Independence. Scientists sunk the carrier in 1951 off the California coast after using it for atomic tests, and now thanks to help from the Navy and Boeing they’ve been able to determine the exact spot where it rests today.
