What will happen to an aircraft if it loses part its vertical tailfin?
Bad things! The vertical tailfin is used for stability and for control over yaw. The rudder is used to control the direction a plane is facing. If this tail is damaged, it would be difficult to control the plane. However, the plane could still land, so long as the landing strip is in a reasonably straight line, since the rudder controls movment left and right.
