A stair climb event set for May 17 at One World Trade Center will help support injured military veterans.

Climbers will be heading up to the 90th floor, or 180 flights of stairs, at the event organized by the Stephen Siller Tunnel to Towers Foundation and the Captain Billy Burke Foundation.  

There will also be a "virtual stair climb," using elevators, for people who want to participate but are not able to handle the stairs.
