Five days after Hurricane Maria devastated Puerto Rico in September of 2017, Bill Keegan, a retired lieutenant with the Port Authority Police of New York, and a band of New York City firemen, police officers and tradesmen from his nonprofit HEART 9/11 were there on the ground to help. Soon after, actor Ramon Rodriguez, with family on the island, told Keegan he wanted to aid their efforts, and raised more than $500,000 for HEART 9/11’s work to replace missing roofs and rebuild entire homes for free.

These heroic Port Authority workers are finally getting their just rewards. The agency’s board has voted to restore an extra yearly vacation day to employees who went above and beyond during the Sept. 11, 2001, terrorist attacks. The move comes after The Post exposed the stingy agency’s actions in removing the “medal day” reward from employees when it implemented cost-cutting measures in 2011. More.

A new special exhibition exploring the almost 10-year search for Osama bin Laden will open on Nov. 15 at the 9/11 Memorial Museum.

No one expected to encounter one of the most deadly, single-day terrorist attacks in United States history on September 11, 2001. The attacks that took place on that day took the lives of thousands of innocent Americans, and the tragedy has taken the lives of hundreds in the years following the incident. More.

Among the helicopter rides, daredevil motorcyclists, livestock and collard wraps, the Robeson County Regional Agricultural Fair had a special exhibit Monday in the form of the 9/11 Tribute Center. The exhibit will move on Tuesday, but fairgoers relived the fateful day on Sept. 11, 2001, when terrorists leveled the Twin Towers of the World Trade Center in a coordinated attack that killed almost 3,000 Americans.

Sunday marked the 18th annual Tunnel To Towers 5K run and walk. Thousands followed in the footsteps of a hero. They were retracing the steps of FDNY firefighter Stephen Siller, who was on his way home on Sept. 11, 2001, when he got word of a plane hitting one of the World Trade Center towers. He turned back around, strapped on 75 pounds of gear and ran through the Brooklyn Battery Tunnel to help save lives. More.

Wednesday marks 18 years since the Sept. 11 terrorist attacks. One of the deadliest days in modern American history. But after nearly two decades, for students from elementary through high school, the attack isn’t a memory. It’s history. A part of their curriculum in a chapter of their text book. Student body vice president at Byrnes High School, Wylie Shaw, understands the disconnect that many of his classmates feel to 9/11. More.
