Be careful that you don't run out of fuel or hit a tower. If you do crash, after Charlie climbs out of the helicopter and kicks the dirt, you will have a new helicopter hovering ready to fly.
When you lower the helicopter to the correct barn, the barn will glow. The helicopter will automatically return to a hover and a new equation will be displayed.
Successfully answer the equations correctly and head to level 2 and 3 with more obstacles to dodge.
