On February 22, 1999, about 1455 eastern standard time, a Boeing 757, N682DA, operated by Delta Air Lines as flight 338, penetrated a flock of birds during takeoff from Cincinnati/Northern Kentucky International Airport, Kentucky. The airplane was substantially damaged. There were no injuries.
The airplane pushed back from the gate, and taxied to runway 18L. While taxing, the crew heard no mention of a bird hazard by another aircraft or air traffic control. The takeoff roll was normal until passing approximately 150 knots; at that point, a flock of starling birds traveling from left to right passed in front of the airplane. The captain advised the first officer of the hazard, and asked him to climb over the flock. The first officer increased pitch angle, but the airplane still penetrated the flock. At the time of penetration, the nose wheel was in the air, and the main landing gear was just becoming airborne. The airplane returned to the airport without further incident. At the time of impact, N1 on the left engine dropped from 81.88 percent to 56.00 percent, and on the right engine, it dropped from 81.25 to 71.63 percent. In both cases, throttle positions remained constant. The bird's roost was not identified, and no airport procedures contributing to the accident were observed.

A flock birds were ingested into both engines, resulting in substantial damage to the engines.
