The The first first two being start game or end fall directing being start game or end fall directing the plane/ planes to a 30 degree the plane/planes to a 30 degree upward incline to the ground. The upward incline to theoccurs ground. The second condition condition occurs when aa second when plane has been hit, thus starting the plane has been hit, thus starting the fall sequence where the place is fall sequence where the place is directed straight to the ground .

Fun Games' BiPlane has the most Fun Games' BiPlane has the most authentic take-off control sequence authentic take-off control sequence of any airplane battle game I've seen of any airplane battle game I've seen yet. It flies just like a real airplane, yet. It flies just like a real airplane, one must get up enough speed to one must flow get up enough speed to createairairflow acrossthe thewings wingstotoget get create across the plane airborne.
