round, silver-colored, shiny, saucer-shaped object flew at a high rate of speed horizon to horizon - taking about 45 seconds

On Coast to Coast, I heard your request for sightings past.
First of all, I am unsure of the date - I put in the above date as a guesstimate since it wouldn't let me submit w/o an exact date.  I do know it was early summer in the early 1950s.  I was approx 10 years old at the time.  I was outside on the front lawn of our home below the foothills in western Wenatchee, Washington.  My mother was doing yard work and both of my sisters (one younger/one older) were outside as well.  We looked up and saw a shiny, silver-colored saucer-shaped object zoom across the sky at a high speed, southeast to northwest. (It was CLEARLY visible.  It must have been fairly close or large - hard to estimate now.) I remember that we all stopped and watched it.  One of us asked my mother, "What is that?"  She responded, "Oh, that must be one of those flying saucers we've been hearing so much about."  A few seconds after the object disappeared over the horizon, a jet plane zoomed over in the same direction.  That's it.  It's a VERY clear memory for me and my sisters.  (Our mother passed in 1962.)
Date is approximate.  PD
