A fast moving light tracking in straight lines appeared in the northern skies........

During a completely clear summer night in a corn field in Kansas, myself and a friend were star looking towards the northern sky trying to find the north star, big dipper and little dipper.  All of a sudden we both saw a very bright light track from the horizon up higher in the sky in a straight line.  It stopped for a second or so then sped directly west in the sky again in a perfectly straight line for a few more seconds.  Then it disappeared totally from the skies.  We at first thought it might be a helicopter, but it was too bright at that distance to be one nd it moved much too quickly.  No way was it a conventional airplane or jet that we'd ever seen.  It wasn't as if one of us was seeing something that wasn't there, cause we BOTH saw the same object.
Date in June 1967 is approximate.  PD
