1. Retired personell connected straightly to UFO stuff, the truth .. what keeps them from leeking the info? (fear of death?losing
family?)
A few different things:
a. no evidence. It isn't like they can take anything material with them.
b. ridicule. Nobody wants to be remembered as a crazy old coot.
c. family, but not in the way you think. They likely have other family members in the military, even in covert ops, etc. who would suffer
financially, etc.
d. illegal. Breaking a secrecy oath isn't taken lightly, and involves some serious jail time, in some cases, even death!
e. then of course, there is the threat of assassination.
f. well compensated. Money talks, BS walks.
g. Some of them HAVE come forward, (Corso comes to mind), but as I mentioned above, they aren't exactly walking out with "proof".
2. Even if you are not retired, how can you live with the truth, knowing other people are like robots, based on mass media?
See the reasons given above, as they apply here as well.
3. What about spy thing: for example: Area51 employee for a huge amount of money taking pictures, collecting evidence somehow to reveal the
truth (never happened as i know of)
You must have never worked (or had relatives who did) in a high security military setting. Its the same reasons you don't see F-117 plans on the
internet.
a. compartmentalized info, only a few know the big picture, the rest involved don't know enough to do any real damage if they come forward, and their
testimony can easily be attacked (character assassination, erasing of public records - see Lazar, etc.)
b. severe security measures (retinal scans, palm scans, restricted to certain areas (again, compartmentalization), electronics to interfere with
recording devices, searches, metal detectors to guard against cameras, etc.
c. all the problems mentioned in the answers to the first question above as well.
4. Infiltrating Area51 for example, has it ever been done, or secret agent thing .. don't think so .. but why?
See the answers to the previous question. For one thing though, I don't believe there are any aliens at Area 51, the base proper. The base is for
just what it is claimed for, the testing of black project aircraft. There are other areas of the base however, (such as S-4, and no, not just from
Lazar, but from other witnesses, and some surfaced documents - see the Security Manual) that do have numerous ties to alien-related tech research (but
not the housing of aliens). If aliens are being hosted by the US, about the only paper trail shreds lead to Wright Patterson AFB.
