Regardless of what you may read elsewhere about the 2002 Crabwood crop circle (google it and read what you will)
The 60 line image of Crabwood is not relevant to the early 1950 TV resolution but to something else. If anything it was saying to look back to a short distance in history...as 60 lins of tv resolution was reminiscent of the 1930's mechanical set. By the 50's we had a lot more lines of resolution happenings. http://www.burnworld.com/dvd/primer/ntsc.htm
re: beyond mechanical TV's of the 30's having under 100 lines (wikipedia) With these systems (far more than 100 lines), the BBC began regularly scheduled black and white television broadcasts in 1936, but these were shut down again with the start of World War II in 1939. In 1941 the first NTSC meetings produced a single standard for US broadcasts. US television broadcasts began in earnest in the immediate post-war era, and by 1950 there were 6 million televisions in the United States.
in the US:
The War Production Board halted the manufacture of television and radio equipment for civilian use from April 22, 1942 to August 20, 1945, limiting any opportunity to introduce color television to the general public.
atom bombs (wikipedia)
the U.S. dropped the nuclear weapon "Little Boy" on the city of Hiroshima on Monday, August 6, 1945, followed by the detonation of "Fat Man" over Nagasaki on August 9.
WWII officially began on September 1, 1939 and ended Sept. 2 1945.
6 years. But lets go back about 10 months from this beginning date to http://en.wikipedia.org/wiki/Kristallnacht
Take that measure from "Crystal Night" beginning to end of WWII and simply double it. Here is where you will be: http://en.wikipedia.org/wiki/1952_Washington_D.C._UFO_incident
The UFO fly over was a response saying to the US: NO you are not the greatest power on earth!
And that is all it was. There was no alien/us military meeting, no agreement. There was no need for one. It was enough of a statement that the US government couldn't do anything about the fly overs. And the world saw this, humbling the US in the eyes of the world. Helped to de-stress world concern over US abusing its atomic power, reducing the overall atomic arms race rate. What you don't see is what would have happened had they not done the fly over. And done at a time when we had better TV communications.
Of course the supposed leaked stories were nothing more than the US government trying not to lose any illusion the rest of the world might have about the US being all powerful. but just a snake that promises to make things better for people in countries its enters, but it only strips away what was and leaves empty the space it stripped away. And that is history.
