ALWAYS REMEMBERED

Today, America and the rest of the world are remembering the 10th anniversary of 9/11 with various activities, most of which are focused on honoring the 3,000-odd victims and heroes of the terrorist attack.

LIFE.com, which "represents the most amazing collection of professional photography on the Web," shares its piece of the commemoration pie by presenting 9/11: The 25 Most Powerful Photos – "25 most stirring, visceral photographs from that day...from the likes of James Nachtwey, Joe Raedle, Spencer Platt, Mario Tama, and other celebrated photojournalists (and one intrepid amateur)." And indeed they are "the pictures we remember: wrenching, indelible photographs that tell the tale of a still-resonant late summer day that changed everything."

One of them though really made me teary-eyed. The pain felt by the man in the picture is so palpable.
