360:, might have selected the wrong audio frequency switches. This, instead of giving him the appropriate Denver low frequency radio range signals, gave him the Denver Visual Audio Range (VAR) course signals. Both of those navigation ranges used the same audio morse code identifier of "DEN." Both of those ranges needed to be received to pinpoint the WONT intersection- the position to which the flight had been cleared by ATC. If the captain had set those switches to incorrect positions, though, so that he was listening to the aural identifiers for the VAR course, he would have heard only the "A" identifier, but not the "N" identifier, which was needed to tell him when it was time to turn left again.

370:, Robert M. Byers, a United Press International reporter, observed the wreckage from a plane and reported that the aircraft had gouged out a path 150' long by 50' wide through the heavy timber, about 8,600' up Crystal Mountain. He also indicated that smoke rose from the gash torn in the trees by the splintering airliner.

At that point, Flight 610 was scheduled to make a right turn to intercept the 168° course line of the DEN low frequency range, and then to proceed to the WONT intersection, its next clearance limit. To intercept that course line, the plane turned to a heading of approximately 210°, which was a proper

identifier of "A", for the north side of that low frequency range. As he neared the course line itself, he would then have begun to hear the "N" identifier, the signal to turn left again, and could track the 168° course line to the WONT intersection.

However, the plane did not turn left, remaining on a 210° intercept heading until impact. At 2:00 a.m. the DC-6 crashed into
Crystal Mountain, about 50 miles NNW of Denver. It skidded 690' to a stop and it burst into flames.

After that investigation, the letter "V" was added to the "DEN" Morse code identifier for the VAR course, to avoid confusion with the DEN low frequency range.
