The object was a brillant white light standing out against the bright arizona sky

I have never reported this before but a local sighting here encourages me. My wife and i were fishing on the colorado river at willow beach arizona some 90 mile or so from las vegas. It was getting dusky down by the river but it was stilll broad daylight above us,no clouds at all. i was laying on my back staring up at the sky when i saw a very bright white light flying over us from east to west. I immediatly jumped up shouted to my wife. Could see no shape just brilliant white light and then it began to move in a sharp zig zag pattern rapidly still going due west. I know aircraft and i knew it was something unusual. Its passed out of sight in probably less than 30-40 seconds. a few seconds later we saw another one just like the first traveling in the same zig zag pattern going west and just as quickly. i was astounded. I remember at about this same time there were reports in the las vegas paper of sightings in the mountains west of the city.
