25 ga Oktoba, 1947, bugu na Bridgeport Post ya ruwaito:

Trailing smoke and flame for at least 22 miles [35 km] before it crashed, the giant ship plowed a smoke-blackened swath for 800 yards [730 m] alongside State Highway 22 [Johns Valley Road] just east of the Bryce Canyon airport. The scene is in southern Utah, about 275 miles [443 km] south of Salt Lake City.

The engines, scorched and twisted, were thrown 200 to 300 feet [61 to 91 m] beyond the burned area, while a piece of the tail – 18 to 30 feet [5.5 to 9.1 m] long – was the largest part of the aircraft remaining. The bodies, burned and unrecognizable for the most part, were horribly torn apart. Two infants and 21 or more women were among the victims, one of the women was an expectant mother. The mutilated remains were flung across the 7,300-foot [2,200 m] plateau or blown into the 200-foot [61 m] deep canyon just behind the impact point. All bodies were left at the scene until this morning, with guards posted to protect them from coyotes.

Pending an inquest, several groups of investigators started official probes today on the cause of the crash. One thing that was known, however, was that Capt. Everett L. MacMillen of Balboa Island, Calif., the pilot, reported by radio at 12:21 p.m. (MST), a few minutes before the incident that fire had broken out, probably in the airplane's baggage compartment, and that the cabin was filled with smoke. Five minutes later, the veteran of 18 years of flying on western routes opened his microphone and reported: 'The tail fire is going out. We may get down and we may not. Best place we can.'

At 12:27, he reported he had turned back for Bryce Canyon airport and said 'May make it. Think we have a chance now, Approaching the strip.' The next radio message came from the airport tower here at 12:32 p.m. It said, 'Fire one mile east.' The ship had gone down at that point.
