The crash of WWII bomber "Heaven Can Wait" killed 11 U.S. airmen. Now 4 are finally being laid to rest.

As the World War II bomber "Heaven Can Wait" was hit by enemy fire off the Pacific island of New Guinea on March 11, 1944, the co-pilot managed a final salute to flyers in an adjacent plane before crashing into the water.

All 11 men aboard were killed. Their remains, deep below the vast sea, were designated as non-recoverable.

Yet four crew members' remains are beginning to return to their hometowns after a remarkable investigation by family members and a recovery mission involving elite Navy divers who descended 200 feet in a pressurized bell to reach the sea floor.
