The Pashinin I-21 page says not to confuse it with this one, but they both use the same pic. Am I the only one who's confused? TREKphiler ^{any time you're ready, Uhura} 19:16, 3 March 2011 (UTC) reply

More confusion - the article text says it is a twin engined aircraft, while the specifications says single engined - as does Bill Gunston's The Osprey Encyclopedia of Russian Aircraft 1975–1995 (although Gunston does say that little is known about the aircraft). Has anyone got the Yefim Gordon book which is alledged to be a reference? Nigel Ish ( talk) 09:39, 9 July 2011 (UTC) reply
