Overnight the National Air Traffic Control System (NATS) went down causing hundreds of delays and cancellations for thousands of passengers at the UK's major airports.
Now, we are constantly told that air traffic is vital for the UK economy and that even though our skies are already overcrowded we need more runways, in the South, to cope. If that is the case then why didn't a backup system kick in immediately? NATS was doubly lucky in this instance in that the fault happened during the quiet night time period and on a quieter weekend. What could have gone wrong does not bear thinking about if this had happened on a busy mid-morning during the week.
