Very large glowing orange shaped sphere and small red flying spheres

In the fall of 1968 my sister and I lived on a farm outside of Ashgrove, Missouri.  One evening my sister and I were at a neighbor's house selling magazines for her high school class fundraiser and while we were there the lights and electricity went out.  Since, we were unable to conduct her magazine business we left and began driving home and I noticed 3 red spheres in the sky.  We watched the red speres flying a incredible speeds, going straight up then stopping, fying across the sky - touching and then  shooting up and down, stopping etc.  We were very excited.  When we gtot home we didn't have electricity either.  We told our mother about the flying spheres and all went outside to watch the red spheres in the sky and at that time noticed back in our woods, we had 175 acres, a very large round, yellow/orange glowing sphere ssitting in our woods.  My mother wanted to go check it out but decided not to because I'm sure she was afraid.  I assume it stayed there all night because later we went inside and I did my homework by candle light.  When we read the local newswapre it stated that on the night of the power outage and our sightings of these objects the power station for the county had been vandalized.  I always thought this was very strange and feel the two were connected.
