Nearly 60,000 Angeleños were informed by Citizen that an airplane had crashed at LAX. Happily for folks worried about an airplane smashing into a terminal, Citizen had disregarded the 'Only a drill' portion of LAX's warning.
ABC7:
A false alarm created a major scare for more than 60,000 users of the Citizen app on Saturday when an alert was sent warning of a plane crash at Los Angeles International Airport.
It turns out the app had mistaken an airport drill for a real disaster and sent "Nearby Incident! Unoccupied Airplane crashed into Terminal at Los Angeles."
Whenever I am feeling too good about humanity, the Citizen app messages me that a neighbor is being stabbed.
