In a tragic incident, a large cargo plane crashed near Fairbanks, Alaska on Tuesday, claiming the lives of the two people aboard. The Douglas DC-4 plane went down along the Tanana River shortly after takeoff from Fairbanks International Airport at approximately 10 a.m., according to a report from the Alaska State Troopers.

Officials reported that the aircraft slid into a steep hill on the riverbank, where it subsequently caught fire. Despite the swift response from numerous agencies including troopers, police, and local fire departments, no survivors were located at the crash site.

As investigations into the crash continue, the National Transportation Safety Board's Clint Johnson mentioned that the cause of the accident remains unknown. Details regarding the plane's operator and its intended destination are also being determined. Johnson indicated that based on the significant post-crash fire, it is presumed that the plane was carrying a load of fuel.

The size of the fire, which broke out in a heavily forested area along the riverbank, initially remained uncertain. However, the Division of Forestry reported that the fire was under control by mid-afternoon.

Eyewitness accounts shed light on the intensity of the crash. Mike Emers, owner of the Rosie Creek Farm across the Tanana River, witnessed the plane's descent. Emers described seeing one of the plane's engines on fire, followed by a massive explosion that reverberated through the ground. He made attempts to contact emergency services but was unable to get through until he reached out to the state troopers.

Emers, along with his son, approached the crash site and described the devastation. The base of the hill was engulfed in a large flame, with debris scattered up to 150 feet along the hillside. The forest surrounding the crash site also caught fire.

Responders, including troopers and other emergency personnel, quickly arrived at the scene using all-terrain vehicles and helicopters. A video captured by Emers near the crash site depicted smoke billowing from the hillside, intermittently punctuated by patches of flames.

This remains a developing story, and updates will be provided as further information becomes available.
