Airlines scramble to get flights in air after planes grounded across US — as it happened

Detailed summary

United States officials lift an order to ground thousands of departing flights at airports across the country.

Thank you for sticking with us throughout our coverage of today's US air traffic control centre outage.

We're ending our live updates here but, as always, you can keep up to date with the latest information on this story and other news via the ABC News website and mobile app.

As we've been reporting to you throughout the day, Australians have found themselves among the thousands of people whose travels have been halted due to the US ground stop order.

My ABC News colleague Kristy Sexton-McGrath has collated some of their stories in the link below.

In the hours after the US Federal Aviation Administration issued an immediate pause of departing flights across the country due to "extraordinary circumstances and reasons of safety", air traffic ground to a halt.

If you're looking to catch up on everything that happened following that order and the impact it had on national and international air traffic, my colleague Audrey Courty has covered it all in the link below:

In other news from the US today, more than 100 people were rescued after a tanker collided with a river cruise boat near the port of New Orleans.

In the aftermath of that accident, the US's National Transport Safety Bureau (NTSB) announced it was launching an investigation and sending a team to Louisiana.

While initially unrelated to today's nationwide halt on flights, both news stories have since merged.
