A 9/11 anniversary tradition is handed down to a new generation

A poignant phrase echoes when 9/11 victims' relatives gather each year to remember the loved ones they lost in the terror attacks.

“I never got to meet you.”

It is the sound of generational change at ground zero, where relatives read out victims' names on every anniversary of the attacks. Nearly 3,000 people were killed when al-Qaida hijackers crashed four jetliners into the twin towers, the Pentagon and a field in southwest Pennsylvania on Sept. 11, 2001.
