Roswell 70 was
the only public event outside the United States
of America that marked the seventieth
anniversary of the Roswell UFO Incident of July 1947. It took place at a pub in
Oxford called The White House (not a joke!) and featured talks by Ben Emlyn-Jones,
Colin Woolford, Miles Johnston and Tony Topping. See here for background: http://hpanwo-tv.blogspot.co.uk/2017/07/ufo-disclosure-2017-70th-anniversary-of.html.
The third talk of the day was by Miles Johnston.
