" A chance discovery by a hiker on a remote Bosnian mountainside could finally reunite the remains of five World War II RAF airmen with their families -- nearly 80 years after they went missing in action. In July 1944, one RAF Wellington bomber among a group of 13 sent from Regina, Italy to attack an oil refinery at Smederevo in Serbia failed to return and nothing more was heard from its crew. Many allied aircraft were lost in the treacherous mountain ranges of Bosnia-Herzegovina, then occupied by the Nazi-supporting Independent State of Croatia. The only gravestone for the five crew from 150 Squadron's flight HF736, and thousands more fliers missing in action was a huge memorial in Malta. But now, Bosnian photographer and hiker Dzenad Dzino has managed to locate human bones and even a gold signet ring believed to belong to the crew, along with wreckage from the plane. And armed with details supplied by his researches, MailOnline has now used RAF wartime records to establish the identities of the five airmen. Only one Wellington with five crew went missing in the area at the time, and that was call-sign HF736, part of 150 Squadron, which went missing on the night of July 16, 1944. We found the 150 Squadron Operations Record book at the National Archives, which stated that 13 aircraft left on the mission in poor visibility, but only 12 came back." www.dailymail.co.uk/news/article-12549703/Hikers-chance-discovery-Bosnian-mountain-solve-80-year-mystery-missing-RAF-Wellington-bomber-disappeared-WWII-raid.html
