It was a day full of ongoing horror that was covered in the media unlike any day before it.

After the initial shock of the day's events wore off, people began demanding answers: How did this happen? How many were killed? Now what?

Newspapers around the country and world took on the job of trying to make some sense of the attacks. Images of the burning twin towers were plastered on newsstands everywhere, below passionate headlines of 'Outrage,' 'Terror!' and 'It's War.'

In the days and weeks following the attacks, information became clearer and more readily available. Now, 15 years later, that fateful Tuesday seems like ages ago for some, but like yesterday for others.
