Based on evidence recorded on AbsoluteAstronomy.com, by writer Gian Piero Milanetti, an airwoman parachuted in the approximate location of the alleged crash landing of Litvyak's aircraft. No other Soviet airwomen operated in that area, so evidence points to the identity of the pilot as being Litvyak, subsequently to be captured by the enemy.
In 2000 a television broadcast from Switzerland featuring a former Soviet fighter pilot was seen by Raspopova, a veteran of the Night Bomber Regiment who contacted Polunina. Before the three regiments were formed, all airwomen trained together. Thus Raspopova and Polunina knew each other although they were to serve in different regiments. See, for example, Reina Pennington's Wings, Women & War, University Press of Kansas, 2001. The featured former Soviet fighter pilot may have been Litvyak.
In the top right Wikipedia page corner Litvyak's rank was erroneously listed as Junior Lieutenant. Indisputably her final rank was Senior Lieutenant. Moreover, her death unconfirmed, the year of her assumed death should be accompanied by a question mark.
