The Day is working on stories to mark the 20th anniversary of the Sept. 11, 2001, terror attacks, and would like to speak to people about the following topics:

• Do you have a vivid memory of where you were and what you were doing when you learned that a jet had struck one of the World Trade Center towers in Manhattan? Perhaps you watched coverage of the second jet being flown into the other tower. We'd like to hear your story. Respond in the space below or email reporter Brian Hallenbeck at b.hallenbeck@theday.com.

• Were you one of the men or women who signed up for military service in response to the attacks? The Day would like to tell your story. Respond in the space below or email reporter Kimberly Drelich at k.drelich@theday.com.

• We're interested in speaking with firefighters and police officers who were in New York on 9/11, but live in southeastern Connecticut now. Email reporter Erica Moser at e.moser@theday.com.
