Family, friends and the military were left with countless unanswered questions. Did the men crash into the icy waters? Were they shot down by Japanese forces? Or were they possibly taken hostage by the Russian KGB? Now over 50 years later, a special US Military force may have finally solved this baffling mystery... After the long and hard battle to win back the Alaskan Island of Attu from Japanese forces, the American military decided to use the tiny island as a launching point for bomber attacks against the Japanese Kurile Islands. During the 500 mile journey, each overloaded plane and its seven crew members faced many obstacles, including enemy fire, frost bite and unpredictable weather. Some bombers made it home, but some did not - including Aircraft 31. The doomed bomber took off on March 25th, 1944 and was never seen again - until now. Suddenly in 1999, a Russian geologist informed American authorities that she had found a WWII bomber at the foot of a volcano in the Russian far east. The US Defence POW/Missing Personnel Office (DPMO) was immediately mobilisaed with three clear goals in mind: identify the plane, account for each crew member and offer closure to the families of the servicemen. MIA: The Fate Of Aircraft 31 follows the work of the Central Identification Laboratory (CILHI), the DPMO's forensic unit, as they venture into the icy slopes of volcanic Mt Mutnovsky. There, they will hunt for bones and personal effects that may help finally determine the fate of the crew, and put to rest the mysteries that have surrounded the disappearance of the bomber. Did Japanese radio really broadcast that they had shot down the plane and taken the crew prisoner? Many other Empire Express planes emergency landed in Kamchatka and became Soviet POWs, could the crew of Aircraft 31 been among them? And did the KGB visit the bomber and tamper with the evidence? Investigators solve these mysteries as they explore one of the world's most treacherous landscapes and a forgotten page of World War II.
