Air New Zealand Ltd. Flight NZ2 should have touched down at John F. Kennedy International Airport Terminal 1 at 5:40 p.m. local time, but a power outage threw operations into disarray, affecting at least 135 flights into and out of the city.

Data from Flightradar24’s website showed the Boeing 787 jet making a U-turn about halfway into its nearly 9,000-mile (14,000 kilometer) journey over the Pacific Ocean, just south of Hawaii. The turnaround made the jet the top-tracked flight on the site, which monitors aircraft all over the world in real time.

Terminal 1 at New York’s John F. Kennedy International Airport will remain closed Friday while operators work to restore flight operations.

“Due to an electrical fire in Terminal 1 at JFK Airport and the terminal’s subsequent closure, NZ2 Auckland to New York was forced to divert back to Auckland,” Air New Zealand said in a statement.
