                                    Pantex Unidentified Object Incident Report



 On September 1, 2015 at approximately 0710 hours, the Pantex Ground Surveillance Radar
 (GSR) detection system identified an unknown object flying in a non-threatening manner west
 of Pantex facilities in a northerly trajectory. The Protective Force (PF) responded in accordance
 with the NPO approved ~curity Incident Response to Unmanned Aerial Systems (UAS} plan. The
 object was initially identified just north of Highway 60 and was traveling in a northerly
 trajectory approximately 10-lSmph. PF personnel were alerted to the object and subsequently
 dispatched t o follow it in an effort to obtain as much information about the object as possible.
 PF personnel on the ground confirmed the presence of the object and maintained observation
 via PF vehicle. PF personnel followed the object for several miles north of the plant until it was
 no longer visible. All plant pedestrian and vehicle gates leading into and out of security areas
 were immediately secured upon identification of an unknown object by the GSR. Furthermore,
 PF patrols moved to a position to ensure the protection of assets.

 A subsequent comprehensive review of the incident was immediately initiated. The following
 text describes actlons taken by Central Alarm Station (CAS) and Secondary Alarm Station (SAS)
 GSR operators, PF officers and Security Police Officers (SPOs) during the event.

 At approximately 0708 hours, the                                                an object
 approximately 1.75 miles SW of Z-12 South traveling at 10-15 mph (see map below titled,
 Ground Surveillance Radar Tracks). Several other radar hits were received as the object
 traversed to the NNW.                                      to attempt to locate the object and
 report its position and direction of travel. A PF lieutenant (Lt.) and SPO in the area spotted the
 object and followed it as it traveled north. The Lt. and SPO attempted to intercept the object as
 it traveled over Pantex Drive in an attempt to view the object directly from below. Although
 they were unable to catch up to the object, they stopped their vehicle and got out. Once
 outside, they noted that the object did not make any sound. Furthermore, the Lt. and SPO
 stated that they were unable to identify any type of propulsion system on the object while
 using binocuJars to assess the object. After viewing it for 1-2 minutes, the object then
 continued north offsite. The Lt. and SPO then followed the object for several miles north of
 Pantex before they lost the object due to lack of roadway access. The location where the object
 was last seen was near County Road G and F.M. 1342. The Carson County Sherriff's office was
 notified when the object began to tr.averse off-site and requested to respond to the area and
 assist in locating the object. A Sherriff's Deputy met the Lt. and SPO at the point where the
 object was last 'Seen. The Deputy stated that he did not see the object but would perform a
 search in the area for anything unusual. It was noted that the object seemed to increase in
 speed and changed direction as it was being followed. The last known direct of the object was
 that it was heading in an ENE direction. The Lt. and SPO were debriefed upon their return to the

 plant. Their perspective of the object was that it was a "diamond" type shape with it being
 more round at the top.

 Security Police Officers in a Bearcat with a Common Remotely Operated Weapon System
 (CROWS) unit were also able to locate and track the object via CROWS camera as it traversed
 the plant. The SPOs stated that it was 100-200 ft. above the ground and they were able to track
 the object for 3-5 minutes. The SPOs location was approximately 75-100 meters from the
 object.

 Other PF personnel that observed the object, including a SPO that was viewing the object
 through binoculars described it as being approximately 4 ft. tall and 2 ft. wide at the bottom.
 The object was also described as being thinner at the top. However, there were some
 discrepancies in the color of the object. Some personnel stated that it was black in color while
 others noted that it appeared to be silver, red and blue.

 Video was obtained from the GSR tower that was closest to the object and subsequently sent to
 Sandia National labs for further study (see image below titled, Image from Ground Surveillance
 Radar Tower). The video does not provide much detail of the object due to the distance of the
 object to the GSR tower. It should be noted that at no time did the object appear to be
 threatening in nature nor did it come to close proximity to any sensitive assets. The object
 remained over open unpopulated areas ofthe plant prior to it proceeding offsite. All evidence
 of the incident {i.e. statements, video, etc.) were turned over to FBI agent
