Narrative:
Upon application of takeoff power, we (the crew) heard a loud 'bang' which I took to be a #2 engine compressor stall. I said 'that's an abort!' to the captain who was doing the takeoff. He replied, 'no, we're going to continue.' airspeed was not a factor as power had just been applied and no other factors were present to indicate we should continue. My eyes were on the instruments but I saw no evidence of any malfunctions and therefore did not press my case for an abort. After climb out, we (the crew) discussed the incident and all decided that it had been the #2 engine compressor stalling due to a 7 KT crosswind. No abnormal engine indications were present at any time during flight and the plane was landed uneventfully at our destination.
