In June of 1967 while waiting in our car to get into a drive-in movie a saucer shaped craft hovered between us and the Wasatch Mountains.

In June of 1967 myself my sister and my mother and father were in our car in line to get into a drive-in movie.  We saw a saucer metalic in color hovering between us and the Wasatch Mountains.  It was approx. three blocks away and was approx. 100ft. from the ground.  It hovered completely still in the air for 20 or 30 seconds.  
Then it went north still quite close to the ground and below the horizon along the Wasatch front and was out of sight in a split second.  
It returned from the north along the same path and was out of sight in the south in a split second. Everybody waiting in thier cars at the drive-in (Woodland Drive-in Salt Lake City, Utah) saw it too.  It was very close and we all saw it clearly.  My other sister and a friend of hers were sitting on the front porch of our home in Kearns, Utah at this time and also saw it.  From our front yard the whole Salt lake valley can be seen to the east.  I have been told that over 200 people reported this sighting.
