UD researchers lead crew to the Adriatic Sea in the hunt for lacking plane
A crew from the College of Delaware, working in partnership with the U.S. Protection POW/MIA Accounting Company (DPAA), just lately situated the wrecks of 5 B-24 Liberator bomber plane that crashed into the Adriatic Sea throughout World Battle II. Of the 5 B-24s, three had been positively recognized and are related to the lack of 23 U.S. service members.
“The situation or relocation of those 5 WWII plane was made attainable utilizing underwater autonomous autos that scan the seafloor,” mentioned Mark Moline, who was the mission chief and is the Harrington Professor of Marine Research in UD’s College of Marine Science and Coverage.
Moline is co-founder of Venture Get better, a corporation that makes use of underwater applied sciences to assist find and repatriate the greater than 80,000 U.S. service members nonetheless lacking from previous conflicts since WWII. Throughout the summer time of 2022, Moline led a multi-disciplinary crew of consultants in the hunt for plane related to lacking service personnel within the Adriatic Sea off of Croatia.
Information and pictures taken of the underwater wreck web site had been used to create this photomosaic of a lacking B-24 bomber. Be aware the propeller within the heart.
U.S. Military Air Corps personnel had been misplaced in massive numbers in Croatia (then Yugoslavia) throughout World Battle II. As U.S. bombers returned from their missions over German-held territory, some had been compelled to ditch or crash in Croatian waters close to an allied airfield. Most of the service members from these plane are nonetheless lacking in motion.
These World Battle II losses occurred practically 80 years in the past, but these lacking from that battle haven’t been forgotten. The U.S. authorities and accomplice organizations, together with UD/Venture Get better, proceed to pursue these investigations with the objective of accounting for the lacking. In accordance with Moline, the method of finding a selected plane begins years earlier than the crew is ready to search on-site.
“Previous to an expedition like this, we conduct analysis and acquire the historic documentation for as many potential losses within the neighborhood as we will determine,” mentioned Colin Colbourn, a UD postdoctoral fellow and adjunct college in UD’s Historical past Division. “This course of, aided by native info and DPAA’s researchers, proved to be important as we had been capable of definitively determine a number of of the plane by way of the small particulars left within the historic document.”
Moline mentioned it was a crew effort that led to those a number of discoveries.
“Whereas finding and documenting these plane is exhilarating, it’s also necessary to do not forget that it’s only step one in a prolonged course of to return these misplaced heroes to their households,” Moline mentioned.

Colbourn added, “Because of our partnerships, this work in Croatia represented a best-case state of affairs. In only some days on-site, we went from scientists and engineers conducting the search utilizing AUVs, adopted by divers and archaeologists investigating the wrecks, to figuring out these plane with historic documentation. The frequency of recent finds and the historic document recommend there’s extra work to do in Croatian waters.”
Advancing know-how
The seek for the lacking plane in Croatia is a component of a bigger innovation effort, sponsored by DPAA, to develop new applied sciences and approaches to finding potential wreck websites. UD’s function on this effort is to reinforce underwater applied sciences and develop new machine studying algorithms to interpret the massive information units collected throughout missions.
Whereas touring by way of the water, the AUVs acquire huge quantities of sonar information that researchers should analyze to find remnants of an plane.
“The plane that we’re searching for are hardly ever intact, which requires extra than simply our human imaginative and prescient to interpret,” mentioned Leila Character, a postdoctoral fellow working with Moline at UD. With a background in machine studying, Character helps the crew develop an algorithm that automates the overview course of, robotically narrowing down the sonar pictures to solely these which can be probably candidates for additional exploration.
World Partnerships
As with all Venture Get better missions, world partnerships are important. J. Tea Katunaric, an archeologist from the College of Cut up, represented the federal government of Croatia and facilitated this mission. Dan Davis, a school member at Luther Faculty in Iowa and the mission’s lead archeologist, credit water depths for serving to protect the crash websites and Croatian companions for helping within the discoveries. The crew additionally benefited from the technical dive and plane experience of Andi Marovic from Manta Divers, who discovered and recovered wreckage items that led to the identification of two plane.

“The Croatian archaeologists, scientists, divers and navy personnel have been terribly skilled and personable,” mentioned Davis. “The quite a few discoveries and plane identifications made this yr are largely on account of their help. The host nation companions are proud to play an element in bringing our lacking service members house.”
The work by Moline and his crew doesn’t finish with the discoveries in Croatia. Missions within the Pacific Ocean are deliberate for 2023 in UD/Venture Get better’s effort towards reducing that daunting variety of 80,000 People lacking in motion.
About Venture Get better
Venture Get better is a collaborative effort to enlist Twenty first-century science and know-how in a quest to search out and repatriate People lacking in motion (MIA) since World Battle II, with a purpose to present recognition and closure for households and the nation.
