The Secret Space Program (S04E01)

On December 20, 2019, the newest branch of the armed services was established – Space Force. But nearly two decades earlier in 2002, a man named Gary McKinnon claimed he had discovered evidence that a secret military space program already existed... after hacking top-secret Pentagon and NASA computers. Does this suggest that the U.S. has a much greater presence in space than the public is aware? Could we even have occupied bases on the Moon and Mars? (History Channel)
