First Lt. Erica MacSwan was just 7 years old when 9/11 happened. Yet, she has vivid memories of it.
Her family lived in New Hampshire at the time. Her dad, who worked for IBM, commuted to New York City for work. On that morning, he was running late for a meeting.
"He didn't get far before a black blanket covered him," MacSwan recalls, "and he just crouched down, and then he couldn't see anything. The city went absolutely silent, which is obviously so unusual for New York City."
