Four airplanes. Four sets of passengers and crews on routine flights on an unremarkable September morning.

American Airlines Flight 11 and United Airlines Flight 175, both leaving Boston toward Los Angeles.

 United Airlines Flight 93, departing Newark enroute to San Francisco.

American Airlines Flight 77, taking off from the Washington, D.C. area headed for Los Angeles.

They would never reach their destinations. Instead, they would be used as weapons on one of the country’s most tragic days, Sept. 11, 2001.

Terrorist hijackers killed thousands at the World Trade Center in New York and the Pentagon in Washington, D.C.

Passengers and crew of Flight 93 attacked the hijackers, thwarting a flight plan still unknown but one that might have been headed for the White House or the Capitol Building.

The crews lost on that tragic are being honored by retired flight attendant Paul Veneto who is rolling a beverage cart along the routes traveled by the ill-fated flights.

The beverage cart symbolizes the cart that flight attendants roll down aisles to provide food and drink for passengers.

Veneto is using the cart to provide a way to remember.

In 2021, he pushed from Boston Logan Airport to Ground Zero in Manhattan to honor United Flight 175.

The next year he rolled the cart from Washington-Dulles Airport to the Pentagon in memory of Flight 77. 

In 2023, he pushed from Newark Airport to the 9/11 memorial in Shanksville, Pa. to remember Flight 93.

The next year, his remarkable journey took him from the commemorative garden at Boston Public Garden to Ground Zero to honor American Flight 11. 

This year “Paulie’s Push’’ represents a final push. He is taking a 220-mile, 28-day final journey from Boston to the Ground Zero 9/11 Memorial in New York City for the 25th anniversary commemoration.

During his memorable journey, he passed through Natick. 

He was assisted by Natick Police Officers Jarrod Marifiote, Ervis Nunez, Cooper Fennell, James Herbert, and Patrick Donahue who ensured he traveled safely through town. 

“The Natick Police Department is proud to support Paulie’s Push and the important mission behind it - honoring those we lost and ensuring their stories are never forgotten,’’ the department said in a statement. 

The department wished him well as he made his unforgettable journey to remember those lost.
