I thought I would repost this comment from Dr. Keith Edwards résumé from 2007 which idicates the US government is working on alien space craft parts:
Here is an excerpt from Dr. Keith Edwards' résumé that he posted on the Internet. Keith removed the smoking-gun part of it after I emailed him in 2007. Here is evidence that he worked on alien parts that the US Government has in it's possession.

The excerpt:
"I got doctorized at Georgia Tech in the venerable discipline of computer science. My old home page has been slowly rotting, but you can visit it to inspect the remains.
From there I moved on to Xerox PARC, where I'm a senior member of the research staff, and get to play with a bunch of the technologies that our government got from the small greys in the abductee-for-tech swap after Roswell.
[[That President Eisenhower approved in 1952 when he met face to face with extraterrestrials at Edwards Air Force Base in California.]]
In earlier past lives, I worked at SunSoft, Sun Microsystems Labs, and the now-defunct Olivetti Research Center (all on internships), and a bunch of places as a consultant, including the now-defunct NeXT Computer.
Going all the way back, I was born in Fredricksburg, Virginia, and grew up in Chattanooga, Tennessee. I'm a leo and my favorite color is blue."
The US government/private industry is up to it's eyeballs with work on alien technology.
