her the title of Hero of the Soviet Union. One of two German pilots is believed to have shot down Litvyak: Iron Cross holder and 30-kill experte Fw. Hans-Jörg Merkle of 1./JG.52, or Knight's Cross holder and future 99-kill experte Lt Hans Schleef of 7./JG 3. Merkle is the only pilot that claimed a Yak-1 near Dmitryevka on 1 August 1943, his 30th victory. (Dmitrijewka is where she was last seen and was – reportedly – buried.) This occurred before being rammed and killed by his own victim (Luftwaffe combat report of collision: 3 km east of Dmitrievka). Schleef claimed a LaGG-3 (often confused in combat with Yak-1s by German pilots) kill on the same day, in the South-Ukraine area where Litvyak's aircraft was at last found. Recognition In an attempt to prove that Litvyak had not been taken captive, Pasportnikova embarked on a 36-year search for the Yakovlev Yak-1 crash site assisted by the public and the media. For three years, she was joined by relatives, who together combed the most likely areas with a metal detector. In 1979, after uncovering more than 90 other crash sites, 30 aircraft and many lost pilots killed in action, "the searchers discovered that an unidentified woman pilot had been buried in the village of Dmitrievka... in Shakhterski district." It was then assumed that it was Litvyak and that she had been killed in action after sustaining a mortal head wound. Pasportnikova said that a special commission was formed to inspect the exhumed body, and it concluded the remains were those of Litvyak. On 6 May 1990, Soviet President Mikhail Gorbachev posthumously awarded her the title Hero of the Soviet Union. Her final rank was senior lieutenant, as was documented in all Moscow newspapers of that date. Controversies Manner of death Arguments have been published that dispute the official version of Litvyak's death. Although Yekaterina Valentina Vaschenko, the curator of the Litvyak museum in Krasnyi Luch has stated that the body was disinterred and examined by forensic specialists, who determined that it was indeed Litvyak, Kazimiera Janina Cottam claims, on the basis of evidence provided by Yekaterina Polunina, chief mechanic and archivist of the 586th Fighter Regiment in which Litvyak initially served, that the body was never exhumed and that verification was limited to comparison of a number of reports. Cottam, an author and researcher focusing on Soviet women in the military, concludes
