Editing Tonopah Test Range (section)

===Sandia National Laboratories===
Operations by Sandia are controlled at the TTR Operations Control Center ([[Area 3 (NTS)|Area 3]]), just southeast of the main airfield, which houses the range safety officer, test director, and key engineers.<ref name="sandia2003" />  Activities are monitored with video, high-speed cameras, and radar tracking devices.  Though nuclear weapons have never been detonated on the TTR, the 1963 test Project Rollercoaster involved the destruction of four weapons, which caused some plutonium to be dispersed into the soil north of Antelope Lake.<ref name="sandia2003" />
