<D>MEMO TO ALL N.I.A.C. PILOTS FROM NATAKA SECURITY<p>A malfunctioning security drone was responsible for the accident that claimed the lives of forty-six Cavalry officers and critically injured thirty-four more. A version conflict on the drone's IFF protocols and an overheated exhaust valve combined to cause the malfunction. All Nataka security drones have been checked for consistent version upgrades since the incident and a comprehensive maintenance program has been implemented. Even without these protective measures we have been assured by Engineering that the odds against this particular equipment fault are over a million to one. Your safety is always our number one priority.</D>
