Good morning, David. Reporter: Good morning, George. The pilots knew they hit a good size bird when they took off from the airport. But they didn't want to land immediately because their a-320 was heavy with fuel. Overnight a jetblue aircraft took off right into trouble. We felt a pretty good jolt. Reporter: The Boston to las vegas-bound jet struck a flock of birds with its left engine. The flight with 144 passengers declares an emergency, attempts to return back to Boston but is denied because of weather.
