— -- A "technical problem" at an air traffic control center more than 100 miles away from Heathrow temporarily grounded some planes at all London airports.
In a statement, NATS, Britain's national air traffic body, said the system had "been restored and we are in the process of returning to normal operations."
Officials at Heathrow said there was a power outage at the NATS control center in Swanwick, which controls all of British airspace.
