her, the girl was too weak to catch he lifebuoy (救生圈) thrown to her, instead, a Comoran police officer,

said Abdilai, jumped into the water to pull the child onto the boat.

although his wife had gone away in this tragedy. He said that his daughter could hardly swim. It was really

a miracle for her to escape in this way. In her daddy's warm arms, the girl could soon remember what she

had experienced."I was thrown out of the plane and then I saw the plane fall into the water. Next I found

the girl.
