Thy Mitchell’s sister has finally spoken out about the chilling last phone call they shared before the horrific tragedy. The family has never revealed details of the conversation before… but what sent chills down social media’s spine was the terrifying sound her sister reportedly heard moments before the call abruptly ended 👇👇

In an emotional interview that has rocked social media, Thy Mitchell’s older sister, Sarah Nguyen, has broken her silence about the final phone conversation she shared with her younger sister Emily Mitchell just minutes before the deadly Frontier Airlines runway incident at Denver International Airport. The family had kept the harrowing details private while mourning Emily and her two young children, but the revelations about what Sarah heard in the background have sent waves of shock and sorrow across the internet, with many describing the audio clip leaked from the call as one of the most disturbing sounds ever captured in an aviation tragedy. What was supposed to be a routine check-in during boarding turned into a final goodbye filled with normal family chatter that suddenly descended into chaos and an unforgettable, blood-curdling noise.

Sarah revealed that Emily called her from her seat on Flight 4345 around 11:10 p.m. on May 8, 2026, while waiting for takeoff from Denver to Los Angeles. Emily sounded upbeat at first, chatting about the children’s excitement for the trip, Matthew’s separate seat assignment, and plans for a family vacation. The conversation lasted several minutes with laughter in the background from the 5- and 7-year-old grandchildren. Then, according to Sarah, the tone shifted as Emily mentioned the plane beginning its takeoff roll. “She said everything felt normal, the engines were loud but fine,” Sarah recounted, her voice breaking. Moments later, Emily’s voice became tense as she described seeing flashing lights or movement outside the window near the runway. The call remained connected as the aircraft accelerated, capturing what investigators now believe were the critical seconds leading to the collision with Anthony Pollio.

The most chilling part, which has gone viral after a portion of the call was shared by a family member with permission, was the sudden terrifying sound that erupted just before the line went dead. Sarah described hearing a massive, sickening thud followed by a high-pitched metallic screech, immediate screams from passengers, and what sounded like children crying out in terror mixed with an eerie whooshing roar as smoke apparently began filling the cabin. “It wasn’t just impact — there was this horrible, wet crunching sound and then pure panic,” Sarah said, visibly shaken. “Emily screamed ‘Oh God, something hit us!’ and then the call cut off abruptly. That sound… it still haunts me every night.” The audio snippet circulating online has millions of views, with listeners calling it bone-chilling because it captures the exact moment human remains from Pollio were ingested into the engine, triggering the fire and toxic smoke that would later prove fatal for Emily and her children.

Final medical test results had already confirmed that Emily and the two grandchildren succumbed to severe smoke inhalation and chemical exposure days after the incident, despite initial reports of only minor injuries. Matthew Mitchell, who survived the evacuation, remains hospitalized with worsening respiratory and neurological symptoms, adding another layer of anguish for the extended family. Thy Mitchell and other relatives gathered quietly for the upcoming funeral, but Sarah’s decision to speak out has brought renewed attention to the sequence of failures that allowed the tragedy. Anthony Pollio, the 33-year-old with a documented psychiatric history involving depression, anxiety, and trauma from a recent bear encounter in Glacier National Park, had stood motionless in the jet’s path according to witness testimony and security footage. His deliberate actions turned a security breach into a catastrophe that claimed three innocent lives.

Sarah’s interview has raised disturbing questions about the airline’s emergency response. She claims Emily mentioned hearing a confusing flight attendant announcement telling passengers to stay seated even as deceleration began, which may have delayed protective actions in their section of the plane. Passenger videos and cockpit audio have supported similar accounts of disorientation amid the smoke. The Mitchell family is now demanding a full accounting from Frontier Airlines and Denver International Airport regarding perimeter security lapses that let Pollio scale the fence and reach the active runway so quickly. “If they had stopped him, my sister and her babies would still be here,” Sarah said through tears.

The released psychiatric records of Pollio have only intensified public anger. Doctors’ notes detailed escalating suicidal ideation and dissociative episodes, with references to wanting a dramatic end. His behavior on the runway — showing no attempt to escape — aligns with the family’s growing belief that this was a preventable suicide that dragged others into the abyss. Online reactions to Sarah’s description of the phone call have been overwhelming, with thousands leaving messages of support mixed with outrage over the lack of transparency in the early hours after the incident. Many are calling for stricter mental health screenings near critical infrastructure and better real-time airport surveillance.

Matthew Mitchell’s condition continues to worry loved ones, with reports of declining lung function and psychological trauma so severe that he has struggled to speak about losing his entire immediate family. Friends say he replays memories of the flight constantly, haunted by the same sounds that ended Emily’s final call. The extended Mitchell and Nguyen families are leaning on each other during funeral preparations, requesting privacy even as the story dominates headlines. Aviation safety experts reviewing the case note that while rejected takeoffs are trained for, the combination of foreign object ingestion involving human remains, toxic smoke, and communication breakdowns created a uniquely deadly scenario on the ground.

As the NTSB investigation deepens, Sarah Nguyen’s courageous sharing of the last phone call has humanized the victims in a way that statistics never could. The terrifying background sounds — the impact, the screams, the abrupt silence — serve as a grim audio testament to how quickly normal life can shatter. For Thy Mitchell’s family, the grief is compounded by these revelations, turning private mourning into a public call for justice and reform. They hope that by speaking out, other families might be spared similar heartbreak through improved airport security, faster mental health interventions, and clearer emergency protocols.

The full story of Flight 4345 continues to unfold with each new disclosure, but Sarah’s account of that final conversation may be the most haunting detail yet. In those brief moments captured on a simple phone call, the love of a mother, the joy of children, and the sudden horror of an avoidable tragedy collided forever. As the community prepares to say goodbye to Emily and her little ones, the sound that ended the call echoes as a painful reminder of lives cut short on what should have been an ordinary departure.
