Not For Disclosure

The Truth about UFOs, the World's Best Kept Secret - The Sunday Times Bestseller from the UK's Leading Barrister

De: Jonathan Caplan

Narrado por: Jonathan Caplan

The most serious and rigorously sourced book ever published on UAPs (Unidentified Anomalous Phenomena), Not For Disclosure reveals a hidden history that challenges everything we think we know.

For over fifty years, Jonathan Caplan KC has gathered extraordinary testimony from scientists, intelligence officers, politicians and military insiders across the world – assembling what may be the most comprehensive body of evidence yet of a reality long denied. When former US intelligence officer David Grusch testified under oath to Congress in 2023 that the United States possesses crashed non-human craft, global attention shifted overnight. But the full story has been kept from the public. Until now.

Caplan uncovers a pattern of secrecy stretching from covert Cold War programmes to alleged presidential briefings and clandestine recovery operations. Spanning sightings, encounters and abductions, and drawing on declassified documents, eyewitness testimony and insider claims, the book explores explosive allegations linking UAP knowledge to figures such as JFK, alongside newly revealed material on secret meetings involving Truman-era officials and the shadowy ‘Majestic 12’ group. Some who came close to the truth, Caplan suggests, paid the ultimate price.

Yet the most profound question remains: are these phenomena visitors – or something far closer, watching and interacting with us in ways we barely understand?

Meticulously researched, deeply unsettling and impossible to ignore, Not For Disclosure is a landmark work that pulls back the curtain on what could be the greatest cover-up in human history.

Superb!

This is the best overview of the UAP subject that I have read, and I probably read 25 per year. It is very well spoken, lucid, and cites sources. Highly recommended. (Audible version)

great book must read!

this is a great book must read on my case must listen to. five stars.

Detailed and interesting

I enjoyed this title, and hearing the accounts as reported by the author around the topic of UAP/UFOs.
Much of what is contained in the book I was already aware of, but it was still engrossing to hear it all put together chronologically and well presented.

Great Summary of where we are as well as some new info!

Great all around book on the ufo subject if you’re new or old to the subject. Where we are currently. How it’s likely to play out. Two new UAP recoveries.

The well-set-out researched facts leading to, in my view, irresistible conclusions

A fascinating book that tackles a subject which has long been the subject of some stigma and ridicule. So much research has been collected to allow the reader to be the judge and jury. I am now persuaded that we are not alone. It raises some huge questions. I encourage you to read it
