Orange glowing ball (sphere) seen in Spokane sky in the Summer of 1975

While laying in sleeping bags in the backyard of our Spokane Valley home on a summer's night in 1975, my older brother and I, at approximately 11:30pm were star gazing the clear sky watching for falling stars when an orange glowing ball (sphere) flew directly above us from east to west.  We could not stop talking about it that night and decided that we would go up into the foothills by our home the next day to search for it.  It seemed so low, like only a thousand feet above us.  I recently read a book called "Search for the Skinwalker" which made reference to a military base in Montana that had logged a glowing round UFO crossing their skies that same night back in 1975.  So I thought I would file a report here and see if any other Spokane-area people witnessed it.
Date in 1975 may be approximate.  PD
