This is an account told to me by my mother that happened in the early 50's.

I was 4-5 years old and don't remember. 
She said we were traveling by car through rural part of Nebraska when a light came from the sky and hovered over our car and the car stalled. She said the light was so bright that she could see every blade of grass as if it were daylight. 
I don't know how long we set there before she said it left and she started the car again and we drove on. 
She is 82 now and still lives in Nebraska and still remembers the details.
Witness indicates that date of sighting is approximate.  PD
