Lake Havasu - 1968 - silent cigar shaped chrome object hanging right in front of me, disappeared in an instant

It was a hot day and a clear blue sky.  I had just shot up a 3 stage model rocket with a lizard payload and was walking thru the desert trying to recover it.  I saw a flash of light come from behind me.  When I turned around, there was a chrome cigar shaped object with no lights or markings just hanging there right in front of me.  It was shaped kind of like a tiny 2 man submarine.  It was totally silent.  I stared at it for about 10 seconds thinking maybe it was a baloon.  Then it dipped to one side (north) and disappeared in an instant.  It was too close to be an illusion.  I remember saying to myself "that was not of this earth!".  I didnt tell anyone or even remember this until the late 90's.  Now I remember it very clearly.  Havent had anything like that happen ever again.
Date is approximate.  PD
