??-??-1948    

       The shape of the objects involved in the Rio and Trindade incidents may be of more than passing interest. You recall that it was a giant metallic sphere which Captain Thomas Mantell reported he was chasing near Fort Knox, Ky., on that fateful afternoon in January 1948. So far as my records show, there were no other sightings of spherical UFO in the northern hemisphere with the exception of one which reportedly sank into the water of a remote Canadian lake, also in 1948.
