It has become a morbid habit for me every Sept. 11 since the attacks: I soak up all the media I can about that day in New York City. I put on DVDs, seek out TV shows on the History Channel, scour the Web for any new videos. My real focus in on the broadcast coverage of that day, watching anchors and reporters — some of them former colleagues — react to the second plane hitting, the Pentagon’s smoke streaming, the towers falling. Archival footage of national and cable news takes me back to an impossibly sunny day and my last week in my midtown Manhattan apartment.
