A remembrance ceremony was held Friday morning in front of city hall. Officials say they did it today so that grade school children could participate.
The keynote speak, Garry McCarthy, was the New York Police Department’s second-in-command when the planes hit the World Trade Center.
McCarthy shared some of his memories of the day on Good Day Chicago on Friday.
"Probably the two most indelible things was first I got there just as the second plane hit the South Tower and a police officer over the radio transmitted and said, 'notify the military, we need air cover. We're under attack,'" McCarthy said. "And as deputy commissioner, I kind of looked at the radio and said, 'I don't think we can do that.' And it was helpless feeling and that kind of stands out."
"But the second thing was there came a point when I was standing in City Hall Park and we heard planes and we knew that all planes in the country had been grounded. And in a millisecond, I saw two F-16's going wing tip to wing tip up the Hudson River in between the buildings. And I had three thoughts, 'oh my God, more incoming' to 'oh, thank God they're ours' to 'oh my God, the military is protecting New York City.'"
