Heathrow: Flights Are Currently Experiencing Delays

A computer failure at the Nats Air Traffic Control Center in South England caused significant flight delays in the UK. The airspace was temporarily restricted but has since reopened, with operations returning to normal. The incident caused chaos, particularly at Heathrow, Europe's busiest hub. The Swanick center, where the failure occurred, has a history of similar incidents, including disruptions in 2008 and a major glitch in 2002.

How quickly did operations return to normal after the incident?

What precedents exist for computer glitches at the air traffic control center?
