Hawaii firefighters marked the 25th anniversary of the September 11 attacks with a stair climb up Koko Head, a quiet tribute rather than a news event.

• Local firefighters climbed the Koko Head stairs to honor the 343 New York firefighters who died on 9/11.
• The climb is an annual tradition meant to echo, in a small way, what those crews faced going up the towers.
• For today's firefighters, the day brings their own crews to mind alongside the families who lost someone.
• Anyone can take part at home by climbing stairs or doing 343 reps, one for each firefighter lost.

Outlook: Expect similar 9/11 tribute climbs and memorial events to continue each year across Hawaii and the mainland.
