What To Know
“Jules, this is Brian—listen, I’m on an airplane that’s been hijacked. If things don’t go well, and it’s not looking good, I just want you to know I absolutely love you, I want you to do good, go have good times, same to my parents and everybody, and I just totally love you, and I’ll see you when you get there. Bye, babe. I hope I call you.”

Brian Sweeney, calling his wife Julie from United Airlines Flight 175.

As the nation marks the 20th anniversary of the September 11, 2001 terrorist attacks, the 9/11 Memorial & Museum in NYC will hold a ceremony beginning with a moment of silence at 8:46 a.m. The names of those lost will then be read by their families, pausing when each subsequent hijacked plane struck the nation and when each WTC tower fell. As the sun sets, the Tribute in Light (88 lights arranged in two large squares atop the Battery Parking Garage in NYC) will shine two beams reaching four miles into the sky, symbolizing the twin towers. The lights will shine until dawn, celebrating the “unbreakable spirit of New York.”
