Oh yeah..... But if it did occur, then I'm sure that a Mr. Alexander Nikolaevich Yakovlev's incredible rolling and turning planes, would have won. Eliptical wings, put to much drag on a plan trying to roll and turn fast/hard. But short and skinny wings, do just the trick.
Fun, fun, fun
Surely at a higher altitude the lack of wing area and therefore lift the yaks would be a sitting soviet ducky.
