Grandmother saw a cigar shaped craft which she said was as long as the valley is wide.

My Grandmother has been dead for a year, and I thought I would report a sighting that she had in the early sixties. 
Her house sits on a hill overlooking the Puyallup Valley and the valley between Sumner and Auburn.  I was just a small child at the time (6 or 7).  I was asleep and she did not wake me. 
The craft that she saw was sunset pink with portholes all around the centerline of the craft.  She said that there was some type of fire at one end (ship was in and out of the clouds). 
The valley is about 1 1/2 mile wide at that point, and she seemed to feel that it was the length of the width of the valley.  That seemed pretty big to me, maybe it was close than she thought it was.  She seemed to think that it was over the city of Auburn itself. 
She said she watched it for about five minutes and then it shot away to the northeast.  If this is the case, it flew in close proximity to the ATC northwest control center in Auburn.  Maybe there is a record of it. 
My mother and she had also seen ufo's in the daylight in the same general area.
