"Initially, when the problem arose, they halted all departures out of the Houston airports and continued to accept inbound planes," Lunsford said.
Controllers increased the spacing between inbound flights as a safety measure. The problem began at about 4:40pm.
"They have been able to restore the system to the point that they're able to allow limited takeoffs and as they bring it back up they'll return to full strength," Lunsford said.
Flights at Dallas-Fort Worth International Airport and Love Field are impacted as well.
By about 6:00pm, the computer problem was completely resolved. Flights are still experiencing departure delays as controllers work to clear the backlog of planes.
