Friday December 12th was not a good day to be flying in any plane into Heathrow Airport in London. London’s airspace was restricted most of the day due to computer failure. The airport announced there was a severe disruption, and they apologize for any inconvenience.
The initial problem is blamed on a technical issue that began in the Swanwick air control centre in the city of Hampshire. London airspace has not closed completely, but air traffic controllers have reduced the plane traffic in order to correct the situation.
Based on what I’ve heard from world traveler Dan Newlin, Heathrow Airport is one of the busiest airports in the world, and they have announced that every possible action is being taken to correct the details that caused this malfunction. Nonetheless, considerable delays are occurring, and many flights have been grounded today.
Departing flights from Stansted Airport, @STN_Airport, are currently suspended as techs continue to work diligently to restore the computer system. Gatwick Airport flights are experiencing long delays also. If you can possibly reroute your flight from these airports, it is strongly suggested so as not to have long wait times.
NATS announced early Friday afternoon that the computer system has been restored, so suspended flights will begin to leave. Delays will continue throughout the day and possibly into the evening, but air controllers expect all operations to be back in operation within 24 hours.
