ERIC T. OLSEN, 41, of New York, was the kind of firefighter who saw good in everybody. “He was somebody you looked up to. He was always smiling, joking and enjoying life,” said his brother, Kenneth. “He led by example.” Although Olsen had just finished his shift the morning of Sept. 11, he went to the scene with his fire company. His family said he was last seen entering one of the World Trade Center towers just 10 minutes before it collapsed. “His first love was being a fireman - after that he loved being a carpenter,” said his mother, Barbara Olsen. He loved to build things and especially enjoyed home improvement projects. Olsen's wife died in 1994.
