Sky Chopper is a rather simple game, where the objective is for you to get to the end of one level to the next.
There are a numerous amount of power ups and you can fly to the bottom of the screen to destroy the tanks, you do not crash into the buildings. I was avoiding the building for a good part of the game.
I played just two levels of it and decided to up it over here since there are hardly any flying games. If you choose to put this game on your blog, extending the height will allow you to choose the primary weapons from a drop down.
