Back-Engineering an Alien Disc: The Galileo, Sidekick, and Looking Glass Projects (1988–1989)
To the point
It claims that life exists elsewhere and that at least one alien craft visited Earth with material held by the government since 1989, and that a former senior physicist worked on a top‑secret reverse‑engineering program (Galileo, Sidekick, Looking Glass) to reproduce its technology, including a reactor needing element 115 in a 223‑gram wedge, and that this knowledge cannot stay secret and would change the world.
