There were lights on the object.
The object left a trail, I observed a sudden, very bright flash of light from a large flying object that appeared to be on fire.
I was 14, and we lived 23 miles East of Yuma AZ, in the tiny town of Dome.
My mother was the school teacher, and we lived in the school building.
I was in the 7th grade that year, and was one of 7 students.
We had no running water, so every night I took a bucket and went to the railroad water car and got the water for the night.
It was a trip of about 1,000' each way.
I was about ¼ of the way to the tracks when there was a very bright flash of light in the sky.
It was bright enough that it cast very black shaddows in front of my body.
I stopped, turned and saw what appeared to be a very large object on fire at about 45° above the horizon, and appeared to be about 10 miles distance.
I could observe what appeared to be structural members, like the beams you would see on a bridge, that were outlined by the fire.
I watched this object move across maybe 30° until it disappeared behind Castledome Butte.
It appeared to be below the mountains to our northeast, and the butte to our northwest, and went below the crest of the butte.
I told my mother what I had seen, and she said it was maybe an airplane, but I had never seen a plane that looked like that.
There were no wings, or tail surfaces, and these would have been visible in the light it was causing.
