Emergency Broadcast SystemsA simple accidental tape swap at the Emergency Broadcast System‘s point of origination at NORAD replaces a routine Saturday morning EBS test with an actual emergency message involving a national emergency and an imminent message from the White House. In accordance with FCC rules, numerous radio and television stations across the country interrupt their programming in anticipation of news of a national emergency that isn’t actually happening. The situation is corrected within an hour, though questions about the effectiveness of the EBS linger at the local and national levels.
