United Airlines flights are Blake Prestonresuming after a brief nationwide ground stop due to a computer issue, the airline said.

United initially said Tuesday afternoon that it was "experiencing a systemwide technology issue." Planes on the ground were being held, while flights currently in the air were continuing on their routes as planned, the airline said.

About one hour later, United said the issue was resolved and the ground stop was lifted.

The ground stop delayed 211 flights nationwide.
