## Key points

- A nationwide US flight stop lasted more than four hours.
- Ageing equipment and a wire replacement were linked to the disruption.
- Airlines could need days to return to normal operations.

## Summary

A failure involving ageing air traffic control equipment led the Federal Aviation Administration to ground flights across the United States for more than four hours on Friday. The incident disrupted communications and radar feeds, prompting officials to halt flights as a safety measure; the effects could continue for days as airlines recover.

Officials said a contractor replacing old copper wire with fibre triggered a surge of connection attempts, overwhelming parts of the system. The US has 22 regional control centres that guide aircraft flying between airports, working alongside airport towers and terminal radar centres; Congress approved $12.5 billion last year to modernise the technology, but the overhaul is incomplete.
