A few weeks ago, Ms. Christie’s phone rang as she was shopping for groceries in Folsom, Calif. Her sister was calling to say that Lieutenant Kelly’s plane — nicknamed Heaven Can Wait — had been found.“I literally walked outside Whole Foods, and I burst into tears,” Ms. Christie said. “And I’m like, where did this come from? I didn’t even know my uncle.”Heaven Can Wait is one of 30 United States aircraft retrieved by
Project Recover, a six-year-old nonprofit that collaborates with the
Defense POW/MIA Accounting Agency, or D.P.A.A., the arm of the Pentagon tasked with finding and returning fallen military personnel.The group says its recoveries show how new sonar and robotics technologies make it far easier to find planes that crashed at sea, and that were once thought lost for good.
