How many people in this subreddit actually know the truth?

I sometimes wonder how many people quietly browse these UFO/UAP subreddits, who have actually been inside the so called legacy programs.
Not necessarily the people at the very top. Engineers.

And I wonder what it feels like to read thousands of us openly debating whether any of this is real while knowing something we don’t.

How tempted are you to say something?

If anyone here has genuinely been involved in something like this, do you ever feel an urge to tell people what you know?
