Esto no es un simulacro

At approximately the 14:00 mark, a character asks aloud if "CONELRAD knows what's going on," then several characters rush over to their cars to tune in their radios. Between 1951-63, CONELRAD (Control of Electromagnetic Radiation) was an emergency broadcast system set up to inform American citizens in the event of an enemy attack during the Cold War. In such an emergency, all US television and FM radio stations were required to stop broadcasting. Upon alert, most AM medium-wave stations would shut down; the stations that stayed on the air would transmit emergency information at either AM 640 or AM 1240--iin fact, most radios manufactured during this time even had special marks printed on their dials at the 640 and 1240 spots). In 1963, CONELRAD was replaced by EBS (Emergency Broadcast System), and in 1997, EBS was replaced by EAS (Emergency Alert System).

After a red alert is announced on the police radio both June and the deputy continue to refer to a yellow alert.

Because the cast was largely unknown, the opening credits list only the director and crew. No actor names appear.
