A U.S. Airman pulls the lanyard to ring a ceremonial bell during a 9/11 remembrance ceremony at Travis Air Force Base, California, Sept. 11, 2025. The bell toll honors first responders and victims of the Sept. 11, 2001, terrorist attacks. In the fire service, the tradition dates to the telegraph era, when a series of five rings repeated four times, known as “Striking the Four Fives”, announced the death of a firefighter in the line of duty and signaled a return to quarters.
