From Sonic Retro
Just pasting this here for future reference...it was in the Miles "Tails" Prower article but since I rewrote that, this little bit of info doesn't fit there. But it should go on this article. It should be put in when the whole thing is rewritten, though.
The Tornado that appears in the Sonic Adventure series and Sonic Heroes resembles the Polikarpov I-153 Chaika, a Soviet biplane from WWII; the I-153's engine is a Wright 'Cyclone'.--David The Lurker 07:14, 18 November 2009 (UTC)
