Many people will discover this just published video interesting:

What the uploader said:
This audio was recorded and sent to a close friend of mine in 2008. The person recording the audio was a government worker based near Groom Lake. Before retirement, this audio was created and sent to a close relative not to be made public for 2 years.

The audio in this and future videos was transferred off a hand held digital tape recorder. This is the first of 3 parts that will be uploaded.

I can confirm the validity of the person who created this recording, however within 2 months of his discharge, the person who created this recording was killed in a "car crash" outside of Dallas, TX. It is the families belief that this was nothing more than a cover, and that telling the truth resulted in the taking of this man's life.
