Narrative:During take-off, just past VR, at a speed of 146 knots, the 737 collided with a flock of pigeons (Columba Guinea). Both engines ingested a number of birds, which resulted in a rise in engine temperature on climbout and the engines backfiring at 100-200 feet. The crew made a right turn to return to airport with the EGT readings at the top extreme. On base leg at 7100 feet amsl with 190 knots, both Pratt & Whitney JT8D-17A engines backfired & flamed out.
