Retired flight attendant Paul Veneto, 64, has embarked on his fourth annual journey from Boston to New York City, pushing an airline beverage cart to honor the flight crews who perished on September 11, 2001. Known as 'Paulie's Push,' his trek follows the flight path of American Airlines Flight 11, which was hijacked after taking off from Logan International Airport. Veneto's cart features photos and names of the crew members, and he aims to ensure their heroism is not forgotten, describing them as 'the first first responders.' His journey, which began with a sendoff from Boston's 9/11 Memorial, involves a 210-mile walk, culminating at Ground Zero on the anniversary of the attacks. Veneto, who worked on United Airlines Flight 175 prior to the attacks, emphasizes the importance of remembering the bravery of the flight crews who fought against terrorism that day. He has previously completed similar memorial walks for other flights involved in the tragedy, attracting national attention and support through social media.
