The New York Road Runners cancelled its fleet of 500 drones less than a week before its annual midnight run event in a decision organizers say was out of their control.

With Dec. 31 less than a week away, the Central Park show could not go on, according to New York Road Runners, the group that organizes the still-happening Midnight Run through the park on New Year’s Eve. The drone show, like the fireworks most years, was meant to accompany the run.
