MOMENTS before United Airlines Flight 175 smashed into the World Trade Center on September 11, 2001, a passenger left a voicemail for the wife he’d left behind in Massachusetts.

“Jules, this is Brian. Listen, I’m on an airplane that’s been hijacked,” said Brian Sweeney, a 38-year-old aeronautics consultant and former Navy pilot. “If things don’t go well, and it’s not looking good, I just want you to know that 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.”

Mr Sweeney called his mother to say he loved her, and tell her the passengers were planning to fight back. “They might come back here,” he said. “I might have to go. We are going to try to do something about this.”

Three minutes later, the plane crashed into the top floors of the South Tower.
