Egg shaped craft near Wahoo, NE

I am documenting this on behalf of my late wife, who directly participated in the event described. For ease of reading, I will proceed using 'first person' format.
 I and my brother were sitting outside our house on an acreage located about a mile south and west of Wahoo, Nebraska. It was early evening, we were looking east ward, and I noticed what appeared to be a bright star.
 As my brother and I watched, the 'star' increased in brightness, then we suddenly realized it was not a 'star', but an object of some kind that appeared to be coming downward...toward us. There was no noise of any kind, and no other lights, such as an airplane usually has.
 When it got near enough to the ground for us to see, it was clearly egg-shaped and shiny. My brother got scared and ran for the house, calling out to Mom (I was about 14 at the time and he was 7 or 8). I just watched as it settled closer to the ground.
 The object looked, to me, as if it were the size of a Volkswagen Beetle. It hovered a bit, and I had the distinct feeling that it was aware of my presence and was observing me. Then, without warning, it zoomed upward and away. I watched it disappear out of sight. Just after it left, my brother and mother showed up.
 Of course, she didn't see anything. My brother was hysterical and ended up sleeping in my mother's room that night...and a lot more to follow.
Witness indicates that the date of the sighting is approximate.  PD
