Origin
The origins of this artifact are unknown. it may have been involved in a crash at some point, as it has minor superficial damage. Despite the name, it was unlikely used in Japanese kamikaze attacks.

Effects
When flown, the wings of the bi-plane create an increased gravity field, causing the plane to quickly lose aerodynamic capabilities. This results in the plane crashing to the ground, making it relatively useless for it's basic function. Despitethe severity of the crash, the plane has a habit of escaping relatively unscathed.
