ET / UFO Recovery / Disposal Document

I accidentally came across this document regarding recovery and disposal of ET/UFO crash site related materials.

On the one hand, I'm hard pressed to believe it's genuine because I don't believe such a classified document would remain on the Internet long enough for me to stumble across it.

On the other hand, someone went to a hell of a lot of trouble to create it if it's fictional. But then again, there is a lot of very convincing fiction out there.

You take a look and decide. I'd be curious to hear other peoples' comments, especially if you happen to know the true origin.
