Neat! That would be cool to find the one in the Mt. Carmel area too.
My take on this one, fuel starvation as there was no post-crash fire. The wings are there so those trees obviously were not there at the time of the crash. Could be engine failure too, since the fuselage is very well intact. Looks like an emergency landing in a field or open area before the trees were there and looks surviveable, although a hard landing can be fatal but the fuselage can look fine. Good example is Jim LeRoy.
What I found on the Mt. Carmel one was that there was a false fire warning in the forward cargo hold. The crew emptied the CO2 bottle to extinguish the "fire" but did not depresurize. They were overcome by the CO2 entering the cockpit so no one was flying the plane.
The Civil Aeronautics Board investigated the crash and published a narrative describing the following sequence of events in its final report:[1]
The airplane, named "Mainliner Utah", arrived in Chicago at 09:52 en route from Los Angeles to New York. After a 52-minute turnaround, the DC-6 departed for New York. The airplane climbed en route to its planned altitude of 17,000 feet. At 12:23, and at 12:27 the crew made a routine acknowledgment of a clearance to descend en route to an altitude between 13,000 and 11,000 feet. A little later a fire warning led the crew to believe that a fire had erupted in the forward cargo hold. They then discharged at least one bank of the CO2 fire extinguisher bottles in the forward cargo hold. Because they did not follow the correct procedure, the cabin pressure relief valves were closed. This caused hazardous concentrations of the gas to enter into the cockpit. These concentrations reduced the pilots to a state of confused consciousness probably resulting in loss of consciousness. An emergency descent was initiated until it described a shallow left turn, heading towards constantly rising terrain. Five miles east of Shamokin the airplane, flying only 200 feet above the ground, entered a right climbing turn. As it passed to the north of Mt. Carmel, the climbing turning attitude increased sharply. The airplane then crashed in a power line clearing on wooded hillside at an elevation of 1,649 feet. The airplane struck a 66,000 volt transformer, severed power lines and burst into flames.
Investigation revealed that the fire warning in the cargo compartment had been false.
Ya, that report was a cut-and-paste.
