NSA had released to the public domain formerly classified UFO X-files
HERE: http://www.ufo-blogger.com/2011/04/nsa-has-released-ufo-files-following.html,
but which had never got media attention.
If the penny hasn’t dropped yet, This now unclassified document not only confirms the presence of extraterrestrials, but that the US Government has received deep space transmissions from a civilization outside our own solar system !
The following is transcribed from Page 21, Appendix:
"Recently a series of radio messages was heard coming from outer space. The transmission was not continuous, but cut by pauses into pieces which could be taken as units, for they were repeated over and over again. The pauses show here as punctuation. The various combination have been represented by letters of the alphabet, so that the messages can be written down. Each message except the first is given here only once. The serial number of the messages has been supplied for each reference."
The following is a copy of the original document as found on the National Security Agency website. You can view the original document at the following location:
