| - | Another range of mountains, most notably a mountain named Camp Creek Bald, form the North Carolina/Tennessee state line would appear on the flight's left, in a southerly direction. These provide a very wide valley, with the two mountain ranges providing excellent landmarks or points of reference to within sight of Knoxville. Present day Interstate Highway 81(non-existent in 1964) runs roughly straight down the middle of the valley, slightly to the north of Ottway, Tennessee. | + | Another range of mountains, most notably a mountain named Camp Creek Bald, form the North Carolina/Tennessee state line and would appear on the flight's left, in a southerly direction.

| The flight was observed on radar to pass Holston Mountain VORTAC (36-26-13.396 N / 82-07-46.462W) at 1757. Up until then there were no indications that United Flight 823 was experiencing difficulties. | The flight was observed on radar to pass Holston Mountain VORTAC (36-26-13.396 N / 82-07-46.462W) at 1757.

| At some time during the descent, the aircraft deviated to the south of V16 but was proceeding approximately parallel to the airway. No reason can be assigned to this deviation. The first witness believed to have seen the aircraft was 38 nautical miles southwest of Holston Mountain. He estimated the aircraft to be 4,000 feet (approximately 5,500-6,000 feet m.s.l) above the terrain and the aircraft appeared to be normal at this time. The aircraft appeared to be normal at this time. The aircraft appeared to be following a nearby river and was about 8 miles south of the airway centerline."** | At some time during the descent, the aircraft deviated to the south of V16 but was proceeding approximately parallel to the airway.

| - | There are two major rivers in the vicinity. The Holston River runs to the north of Bays Mountain. The other is the Nolichuckey River that originates in North Carolina. It runs along the foot of Camp Creek Bald and the Tennessee/North Carolina state line. If one takes a ruler and measures the mileage scale on an ordinary road map, it is plain to see that the report meant the river as being the Nolichuckey which would be approximately eight miles south of the V16 centerline. | + | There are two major rivers in the vicinity.

| According to the Civil Aeronautics Board Report, both the primary and secondary radar targets disappeared at 1813:30, precisely 15 minutes and thirty seconds after passing Holston Mountain and approximately 10 minutes and 30 seconds after the crew's last radio transmission. | According to the Civil Aeronautics Board Report, both the primary and secondary radar targets disappeared at 1813:30, precisely 15 minutes and thirty seconds after passing Holston Mountain and approximately 10 minutes and 30 seconds after the crew's last radio transmission. | ||
