Have one of your teammates get in the driver's seat. Have them hold L2 so that plane gets very low to the ground. Have yourself and whoever else around pile onto the plane. You can stand just about anywhere on either plane, but try to stay away from the sides. Crouch to keep from falling off. Make sure to have at least one rider with a rocket launcher. The pilot should never leave Hover mode and not make any sudden movements . Planes may be able to exit troop boundaries, but the riders cannot -- stay in the boundaries. The plane will sink a little with people on it. Just go up if you get too low. You can then carry your troops to the enemy base. This is also useful in Capture The Flag because you are not allowed to fly with the flag.
