On September 11, 2001, al-Qaeda terrorists hijacked four commercial airliners, and crashed two of them into the Twin Towers of the World Trade Center in New York City.
Another crashed into the Pentagon, and a fourth plane crashed in rural Pennsylvania after passengers put up a fight against the Islamic militants.
Nearly 3,000 people were killed and the attacks triggered a decades-long global war on terrorism.
Stair climbs have become a way to honor the victims who died 22 years ago Monday.

The idea is to climb an equivalent of 110 flights or 2,200 steps that represent the World Trade Center.
Monday morning, there was a memorial stair climb at Rice-Eccles Stadium on the University of Utah campus.
It’s Navy Week and servicemen and servicewomen as well as ROTC students at the U took part in Monday’s stair climb.
“What victim’s family members want more than anything else is to remember what happened that day on 9/11,” said Rear Admiral Aaron Rugh with the U.S. Navy.
