Thanks! Although that's a bit disappointing, I guess.
The Biplane in game seems to be primarily a Reconnaissance and Anti-Reconnaissance piece. IF the enemy builds Biplanes, you can attack them, otherwise it's just to reveal where the enemy is.
That's completely Historical, since the first military aircraft were all reconnaissance only and it wasn't until the very end of WWI that aircraft could carry enough ordinance to do any real damage to anything on the ground except under very, very favorable circumstances (like, Turks with horses trying to retreat across an open desert with no antiaircraft or air cover in Palestine). For 'real' Air Power, you have to wait until the Modern Era, I suspect.
