Narrative:

Shortly after the flight took off; I received a call from the crew stating they had heard a thud and perhaps it was a bird strike. Maintenance control was brought into the conversation and it was determined there were no abnormalities with the aircraft and it was safe to continue on. Since it was a possible bird strike; an inspection was set up to be done on arrival. Approximately four hours later; our airline operations manager received a call from airport operations duty manager stating that some debris had been found on the end of the takeoff runway; and they suspected it could have come from our flight (due to timing and report of possible bird strike). I was advised and called the manager to get more information. After hearing that there were multiple pieces of aluminum found; I requested some pictures of the debris and asked to set up a call with our maintenance manager. In the mean time I advised the crew of the debris found. After speaking with the crew; even though there were no abnormalities and we did not know if the debris came from our aircraft; the crew wanted fire trucks to be available as precaution only. After receiving the photos and speaking to the manager; our maintenance people said it was highly unlikely that the debris had come from our aircraft. I then advised and in turn advised the crew. By that time the flight was in the process of landing. No emergency was declared and the landing was uneventful. However upon inspection; the number 2 outboard engine acoustic liner section was missing. I was told the liner could have come out due to metal 'fatigue.'
