They gave that research to Project Recover. The group of marine scientists, archeologists, and historians went to work using science and advanced technology to find missing aircraft with servicemen still onboard.
"It's really easy to look on a map and say 'Hey, x marks the spot and it turns out that x could be several square miles,'" said Eric Terrill, Co-Founder of Project Recover and a Scripps Oceanographer
In October 2017, Terrill and his team set out on a three-week expedition.
"These robots allow us to do very detailed surveys of the seabed using scanning sonar," he said.
Today, there are still more than 72,000 missing U.S. service members from WWII.
"There are stories like this all around the country of an uncle or a father or a grandfather that never returned home," Terrill said. "It's remarkable to think that [families] carry this loss for that many decades and then to actually see it play out is just amazing."
Lieutenant Kelly's family has already been in contact with the families of seven other crew members on the plane. They're hoping the military will recover the remains from the wreckage.
