I CAN’T GUARANTEE THE AUTHENTICITY of this document, although the context pretty much describes the truth as it is. We don’t know when it was written and exactly by whom, but it looks like it was composed by a British person if we look at the spelling of words, which is British English.
This information was sent to me by someone who for obvious reasons wants to be anonymous. This person gave me this reply when I asked if he/she could verify the authenticity of it:
“The document was passed to me by a gentleman who has long been a researcher into these things and it was meeting him that first caused me to search the web for more information. That’s how I came across your site. I think he was afraid to let me see it at first as he was unsure I could be trusted. He told me there are those who would kill to stop this information getting out. You will understand why I cannot reveal his name – I only know him by his first name anyway; he wouldn’t reveal his surname. I believe he works as a member of an aircrew, but precisely where I don’t know.
