People hundreds of miles apart all saw the same green fireball in the California sky. Video shows what looks like an asteroid fall towards the earth, and the United States strategic command say the object is probably not man-made. Whatever it was, it was visible from the Mexican border to the northern part of Ventura County.
United States Strategic Command (USSTRATCOM) is one of nine Unified Combatant Commands of the United States Department of Defense (DoD). It is charged with space operations (such as military satellites), information operations (such as information warfare), missile defense, global command and control, intelligence, surveillance, and reconnaissance (C4ISR), global strike and strategic deterrence (the United States nuclear arsenal), and combating weapons of mass destruction.
For the time being, no one knows what it was.
