HERE IS Gary McKinnin, a Computer Hacker from England.
In 2001 whistle blower Gary McKinnon, a British citizen and computer genius claimed to have hacked into 53 U.S. government agency computer systems including the U.S. “Space Command Network”, where he found evidence of an off-planet military mission. “I found a list of officers’ names under the heading ‘Non-Terrestrial Officers’… 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 U.S. Navy ships. What I saw made me believe they have some kind of spaceship off-planet.”

In 2015 William Tompkins, a retired Naval engineer and author of “Selected by Extraterrestrials”, verified McKinnon’s claims with astounding revelations that this “Secret Space Fleet” does in fact exist and that its creation is directly linked to the Nazi saucer projects of World War II.

Tompkins himself actually claims having worked over a 12 year period, beginning in 1951, for an Above-Top-Secret think-tank within the Douglas Aircraft Company, designing a kilometer-long antigravity spacecraft covertly commissioned by the U.S. Navy.
As a teenager, William Tompkins’s keen eye for crafting detailed war-ship models caught the interest of the U.S. Navy which recruited him into Intelligence programs to work on advanced technology projects.

Due to his exceptional skills with Naval Intelligence, beginning in 1942

Tompkins directly participated in top-secret debriefings of Navy spies embedded within Nazi Germany’s most secret aerospace facilities during and immediately after World War II.

Although only a third class seaman, he replaced a Commander at North Island Naval Air Station in San Diego.
USSS Hellencoetter, was the name of one of the large shops of the Space fleet.
