42 years ago and I don't remember about the detalis below; maybe some were present.

Meeting At Plaza Cívica with over 100,000 witnesses. One bright dot appeared on the horizon at NNE. Faster than a satelite traveled to the top of the meeting, Stopped Abruptly for a few seconds and then descended verticaly very fast until its shape was clearly seen as a grey disc. Stopped for about half a minute and gave time to take pictures and movies and then ascended vertically extremely fast until it appeared again as a bright spot. Then it stopped again abruptly and stayed inmovil for 4 or 5 seconds and then went SSW extremely fast (much faster than a satelite) and dissap- peared in the horizon. *** Many people took movies or photohgraphs. I took several pictures with a Zeiss-Icon camera which I had to leave with my family when I left Cuba on Oct 15 1961. *** Several pictures were published in the following news-papers: "Diario de la Marina", "Información", "El Mundo" "El Pais"and probably others too. I saw the pictures at the above mentioned newspapers.
My photographs were developed at the "Hutterly Store", one of the best or even the best in Cuba. There were hundreds of privately taken pictures or movies.
I do not know if this event was published in USA.
