Biplane

<p>168, Republic City, URN: Hiroshi Sato, founder of Future Industries, invents the biplane based on earlier designs created by Councilman Sokka (I'd like to think). </p><p>170, Republic City, URN: Equalist forces use biplanes manufactured by Future Industries to attack the United Forces during the Battle for Republic City. Soon after, Future Industries (now under the control of Asami Sato) starts commercially producing planes. </p><p>171, Southern Water Tribe: Varrick keeps a personal biplane on his flagship, and another on his battleship, the <i>Zhu Li</i>. Asami flies both of these. </p><p>174, Yi, Earth Kingdom: Bandits use a biplane to raid an Air Nation food harvest. </p><p>
</p><p>...What? How? Who? <i>Why</i>? I mean, one minute they're top secret revolutionary machines, the next minute basically <i>everybody</i> except any government that might actually <i>use</i> them <i>has</i> them. Planes have appeared so little, and yet the lowest of the low seem to have them while the more "sophisticated" groups (like armies, for example) haven't really used them much, if at all. Permit me, as a airplane fan and amateur historian, to let out a very troubled "Huh?" </p>

<p>Although people keep saying that the United Forces used biplanes, they didn't.Future Industries did.Here are pictures to prove my point. </p><p>I know Future Industries could've just let the UF use them, but... </p><p>On an interesting note, the biplanes that were failing to deafeat <i>Unuvattu</i> were armed with torpedos.It kind of makes sense; I mean what else would they shoot at him? </p>

<p>In the final episode of Book 2, when Unavaatu attacked Republic City I saw a formation of biplanes trying to attack the dark avatar from above but failed with the latter grabbing one of them and destroyed it though the pilot ejected for safety. </p><p>Were the biplanes integrated into the United Forces after Amon's revolution? </p><p>Please post your comments about this thank you! </p>
