ATLANTA (AP) — A passenger plane has landed safely after passengers were told it struck two birds taking off from Atlanta.

The Delta flight, operated by regional carrier ASA, was on its way to Mobile, Ala., when passengers said they heard a loud thud.

The pilot told passengers the plane would circle over northwest Georgia to burn off fuel before returning to Atlanta.

ASA spokeswoman Allison Baker says the 50-seat CRJ-100 hit what officials believe were two birds, but their species has not been determined.

Passenger Sarah Burch, the wife of the executive producer of WKRG-TV in Mobile, told the station she could see damage on the plane’s nose and right wing after leaving the plane.
