According to McKinnon, he had first hacked into NASA's Johnson Space Center :
"I found a high definition picture of a large cigar shaped object over the northern hemisphere. I was so shocked by the picture that I didn’t think to immediately save it. The file size was so large that it was difficult to view it on my computer. Eventually my connection was lost, and so was the picture."
When McKinnon later hacked into classified files of U.S. Space Command (incorporated into Strategic Command on October 1, 2002 soon after McKinnon was caught), he discovered a number of naval terms such as "fleet-to-fleet transfers" concerning non-terrestrial officers. He said:
I found a list of officers' names … under the heading 'Non-Terrestrial Officers’. It doesn't mean little green men. What I think it means is not Earth-based. I found a list of 'fleet-to-fleet transfers', and a list of ship names. I looked them up. They weren't US Navy ships. What I saw made me believe they have some kind of spaceship, off-planet."
McKinnon’s startling discovery cast light on what had been earlier revealed by no less than a former President of the United States: Ronald Reagan. In President Reagan's Diary, the entry for Tuesday, June 11, 1985 (page 334) reads:
Lunch with 5 top space scientist. It was fascinating. Space truly is the last frontier and some of the developments there in astronomy etc. are like science fiction, except they are real. I learned that our shuttle capacity is such that we could orbit 300 people.
Reagan’s comment was revealing since the recently retired Space Shuttle held a maximum of eight people and only five were built for space flight. Even if all five took off fully loaded it would be impossible to place and maintain 300 astronauts in orbit. Was Reagan revealing the existence of a highly classified space program that could accommodate hundreds of astronauts in orbit? Apparently so, according to dozens of military and corporate whistleblowers. Hidden within one of the nine unified combatant commands of the U.S. military, as McKinnon later discovered, appeared to be a highly classified fleet of aircraft carrier sized ships (similar to which we saw in Avengers 2012 movie) that operate in outer space.

Now that McKinnon no longer faces the threat of extradition and is unlikely to be prosecuted by British authorities, he may be able to reveal more about what he learned from sensitive U.S. military and government computer files about UFOs and extraterrestrial life.
