1970 Sighting over Kirtland Airforce base in New Mexico.

I wrote about an experiance I had with my firend earlier in Denver. I spoke to my mom about it and she reminded me of a story of when i was only six months old. 
My Grandmother was driving, my father was in the passinger side and my mother was in the back seat with me. They were by Kirtland Air Force base late in the evening.  I was just a baby. 
The surounding area was not built up yet, so most of it was field.  By the field there was this huge object.  
My mom said it was one shape than it transformed into another, almost like a crown.  She said that they lights were moving down the side of it were brilliant and colorful and we still don't have any technology like htis.  She said that all three had gotten out of the car to look at this object.  She said it was huge. 
The lights were very phospherious and then it was just gone. She tells me this same story all the time, but she is afraid to talk about it publicaly.  Especially because at the time my father was a military man.
