## Key points

- Investigators are checking for installation error or a faulty router.
- The outage began during a telecommunications upgrade by L3Harris.
- Duffy renewed his call for $50 billion in air traffic control funding.

## Summary

Investigators are examining whether a contractor’s mistake or faulty router caused Friday’s nationwide US aviation ground stop, but the cause remains unknown. Transportation Secretary Sean Duffy said a cyber attack is not believed to be responsible, though it has not been ruled out.

The outage began while federal contractor L3Harris was replacing copper telecommunications wires with fibre optic lines at a remote location. Duffy criticised the contractor and said the work should have been completed years ago; he renewed his call for Congress to approve $50 billion for a new air traffic control system. The disruption stranded thousands of travellers, while the article’s headline says a million fliers were affected.
