My friends and I were sitting on the roof of a building and saw 6 rows of 6 stars in formation then did a 90 degree turn in formation

In 1952-53, my friends and I have seen numerious sightings in the Bronx, NY  In one case about 6 roes of six (looked like stars) moving in one direction than all turned 90 degrees at one time in formation.  Another summer night a round disk houvered over the intersection of Barns and williamsbridge Road. About 70 people observed it.  Suddenly it moved slighty and was gone in a flash.  The last one may seem strange but true.  I was walking at night on a quite street (I was about 9 years old) I had a strange feeling and looked up into the sky, I saw a star moving as if following me.  I walked about 1 1/2 blocks and stopped. I did an about face and started walking in the opposite direction.  The star did a sort of u turn and started moving with me.  Initally I was frighteded but later felt that it was some kind of good sigh.  I would be willing to be interrogated buy any skeptic even under truth serom.  It did happen
Witness indicates that date of sighting is approximate.  PD
