Once is happenstance...
Twice is coincidence...

Japanese public broadcaster NHK issued a North Korean missile launch alert on Tuesday evening—but, like a warning issued in Hawaii over the weekend—it turned out to be a false alarm.
The alert was published on the news channel's website and sent to thounsands of people who use the company's news app. Within minutes, the mistake was corrected. The broadcaster later published a clarification and apology on its website.
One Twitter user who received the alert said it read: "North Korea appears to have fired a missile, evacuate inside a building.” Five minutes later, another alert said it was a false alarm.
