What happened during the crash landing of Delta Flight 4819?

During the crash landing, the plane hit the runway extremely hard and began leaning to the left. The aircraft then skidded on its side before flipping completely upside down and bursting into flames. John Nelson, a passenger, described feeling intense heat through the glass windows as a 'giant firewall' formed along the side of the plane. The impact was so severe that the tail and one of the wings were completely torn off the aircraft. Despite the catastrophic nature of the crash, emergency responders including air traffic controllers, paramedics, and firefighters quickly sprang into action, helping ensure the evacuation of all passengers and crew.
