Kazakhstan builds world's first ET embassy

among the gems in this little piece are the assertions that
1. A UFO 'crashed' in a Kazakh river in '08
2. It's widely accepted over in former Russkyville that there is a UFO base underwater in the Caspian Sea, and
3. The USSR regularly monitored UFO comings and goings out of said base
WOW!
I never heard of any of that before just now. Gotta do some more research on those ones....

Soviet UFOlogy, some history and context

A few gems of real interest concerning the history of UFOlogy in the Soviet Union in the 70's and 80's, including a brief retelling of the famous case where a 900m-wide UFO prepared a Ukrainian Missle base for launch of its nuclear missles...

Good reading for context as concerning the various secret government UFO research efforts throughout the cold war (as far as we know), and for some eyebrow-raising stories of soviet fighter pilot encounters with mile-long 'black clouds' etc...
