crash, is reported to have said, "I think an act of heroism just took place on that plane." Crash At 10:03:11, near Indian Lake and Shanksville, Pennsylvania, the plane crashed into a field near a reclaimed coal strip mine known as the Diamond T. Mine owned by PBS Coals in Stonycreek Township in Somerset County. The 757 had between of fuel remaining, which exploded and released a fireball that scorched a nearby hemlock grove. Far-flung debris that made up a third of the aircraft, including the cockpit, continued into the woods, demolishing trees on owned by the Lambert family, and damaging the nearby residence of Barry Hoover. The rest of the aircraft buried itself in dirt that had been transported to the abandoned strip mine for reclamation efforts in the 1990s. The fuselage and wings shattered as they burrowed into the earth. One of the engines ultimately ended up in a catchment pond just away from the main impact site. The National Transportation Safety Board reported that the flight impacted at at a forty-degree nose-down inverted attitude. The impact left a crater deep and wide. The coroner ruled that everyone on board who was still alive at the time of the crash died instantly of blunt-force trauma. Many media reports and eyewitness accounts said the time of the crash was 10:06 or 10:10; an initial analysis of seismographic data in the area concluded that the crash occurred at 10:06, but the 9/11 Commission report states that this analysis was not definitive and was retracted. Other media outlets and the 9/11 Commission reported the time of impact as 10:03, based on when the flight recorders stopped, analysis of radar data, infrared satellite data, and air traffic control transmissions. The only known witness to the actual crash, and the last one to see United 93 airborne, was Stoney Creek resident Nevin Lambert, who reported that he saw the plane upside down as it crashed to the ground in a 45 degree-angled nosedive. Kelly Leverknight, a local resident, was watching news of the attacks when she heard the plane. "I heard the plane going over and I went out the front door and I saw the plane going down. It was headed toward the school, which panicked me, because all three of my kids were there. Then you heard the explosion and felt the blast and saw the fire and smoke." Another witness,
