There will NEVER be "Disclosure" and I have been saying that since 1997 when some of the first grifters announced "UFO Disclosure is next year",
Back in the early 1980s I used to meet up with an American gentleman I had corresponded with on UFOs since the 1970s. I knew what his work was supposed to be but I also knew who he worked for (that is a semi funny story in itself).
We would meet and exchange UFO reports and items of interest and he would have a short list of any questions such as "Have you come across-----" or "We've found this feature in some reports -have you and any idea what it might mean?" and so on.
I had similar conversations with persons attached to the UK MoD and the one thing I learnt was that official bodies had UFO reports, they had photos etc but they were no nearer to having anything solid than UFO groups.
There are no frozen bodies and certainly not, at my last count, well over 100 crashed alien space craft -just think that through logically Travel through interstellar space with such poor technology that every flight is a suicide mission OVER 80 years -no advancement.
I was unofficially at a certain US base in the 1980s looking into a UFO report. Nothing "Top Secret" though the visit was later distorted out of reality on the TV series UFO Hunters.
So if you think any government is going to shatter everyone's world view and release sensational cases that cannot be explained...think again.
