WARNING: CONTAINS SENSITIVE AND DISTRESSING CONTENT
People are heartbroken by the voicemail a passenger on United Airlines Flight 175, which crashed into the South Tower of the World Trade Center on 11 September 2001, left his wife after the plane had been hijacked by terrorists.
Brian David Sweeney, who was from Massachusetts, had been travelling from Boston to Los Angeles when his plane was hijacked by al-Quaeda terrorists, who diverted the journey to New York.
All 65 people onboard were killed.
Before the plane crashed, the former United States Navy pilot was able to call his wife, Julie, and leave her one last message.
In the voicemail, he said: "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."
His story was recently shared in a TikTok video by @factsandtheorieshub, where many social media users commented to say how heartbreaking they found Brian's message.
One person said: "Damn, this broke my heart dude."
Another added: "Omg my heart."
A third wrote: "Imagine waking up, hearing planes crashed into the Twin Towers, and then checking your voicemail and seeing this."
Another said: "The 'I'll see you when you get here' just heartbreaking."
His wife Julie has previously said she was incredibly 'thankful' for the message he left her, saying it was 'very powerful'.
In a 2014 video made for the 9/11 Memorial and Museum, Julie explained: "You hold out this hope, especially for someone like Brian, who - this is a silly way to put it - but he was a warrior.
"And you just didn't believe that something like this could take him away. So you hold out this hope until it's validated somehow.
"And all I needed was that message. And I think he very selflessly left it. I don't think he left it until he knew that he wasn't coming home.
"When I got it, it was just so Brian. It was his final request of me, and his final way to let me know that he was gonna be okay, and that he believed that he'd see me again. And that's all I needed to know."
She continued: "I'm thankful for it. So thankful for that message because, at least I know without a shadow of a doubt, what he was thinking.
"The calmness in his voice soothed me. So I do have that. And because it's on a message, I'm able to share it with anybody that wants to hear it.
"And it's very powerful. He made very powerful statements with that message."
