1.   Wreckage in the vicinity of the break point fell first and was recovered in the westernmost of three major debris fields.

2.   An area recorded by sonar imaging a half-mile from the wreck, which seemed to be a debris field, also will be examined.

3.   Another disappointment, investigators said, was the meager return from a new sonar sweep in the debris field closest to Kennedy International Airport.

4.   As they moved, the crews left behind clean patches in the debris field.

5.   Besides, Taylor said, simply walking around in the debris field under such soggy conditions was a bad idea.

6.   A front section of the horizontal stabilizer measuring about five feet also was spotted in the debris field.

7.   A mesh net will be dragged through the ocean, away from the debris field, to collect remains.

8.   A third debris field sprinkled with luggage and tiny scraps of metal underscored the suspicion for everyone that the malfunction theory was fantasy.

9.   A small moving mirror reflects the laser beam back and forth across the bottom, as a light receptor builds up an image of the debris field.

10.   A three-mile perimeter has been established around the debris field, officials said.
