The expedition is the fourth to be carried out by the RGS to several Gulf of Finland islands, and is sponsored by the Russian Defense Ministry and the Leningrad Region administration. Some 100 Russian servicemen and 20 units of military equipment are taking part in the expedition alongside volunteers and Rossiya Segodnya International Information Agency journalists.
On Wednesday, the RGS expedition on Bolshoi Tyuters located the site of the wreckage. An expedition member cautioned that finding the remains of all of the plane's crew members is unlikely.
"The [discovered] parts of the plane coincide with the technical description for the Pe-2 bomber," Pochernikov said.
Bolshoi Tyuters was occupied for three years by Nazi forces and detachments equipped with autocannons were stationed across the island.
An international Russian-German expedition has also been exploring the islands of Bolshoi Tyuters and Gogland, seeking to find the remains of fallen Soviet and German World War II soldiers, and exhume them before reburying on the mainland. The remains of over 120 German soldiers are estimated to be on the islands, according to the German War Graves Commission.
