This book examines self-reported alien abduction cases in the North American region, and compares and references to declassified, leaked and rumoured advanced military technology and psychological warfare techniques.

Dr Lammer and his wife work towards the thesis that reported alien abductions and sightings are not aliens at all but rather top-secret US military operations.

He supposes that American citizens are being abducted and experimented on, to various ends, and fooled by theatrics and hallucinogenic drugs into thinking it was aliens as a cover story.

The designs of these abductions range anywhere from MKULTRA mind control experiments and microwave implants, to create perfect spies and assassins, genetic alteration, as well as human cloning. And of course, any ethically dubious scientific experiment that would cause outrage if made pubic.

It's quite hard to explain in a concise way, and the available information is so clouded and disparate it's an uphill battle to prove anything conclusively. The authors do go out of their way to make clear that much of what is written is pure speculation and ought not to be taken as fact.

And that is my main issue with the book. The thesis hinges upon self-reported alien abductees not being schizophrenic and insane. To counter this, Lammer tracks independent reports with general trends. For example, unmarked black helicopters began appearing in accounts during the late 60s and early 70s, all near military air bases, and similar accounts of victims seeing people floating in fluid-filled tubes. There are quite a few more I can't be bothered to write down, but the same sorts of aliens and the same sort of military personnel appear often.
