Well from what Ive seen and heard I can pretty much guarantee you its there. As a matter of fact people use to climb the hills and mountains that bordered that facility and they would or should I say (could) observe operations or what was going on there on the outside.
The government had found this out due to press releases, stories and PICTURES from theseo people observing and had then put restricted area signs so the people could no longer get to those observing areas. Now people can only get within 15 - 20 miles of that facility and its monitored with gaurds around the clock.
If you do a search there are scientists and other workes that had gotten sick there years ago and there was actually a lawsuit that the workers won!! I believe a scientist or a worker had died and that finally set the employees over the edge to follow through or persue with the lawsuit.
If that facility eve shuts down they will still have it restricted I can assure you that
people have pictures of workers digging holes and pushing damaged and smashed up or crashed aircraft into them and covering them with dirt. They pretty much in the pasthad said there is no area 51 but realized people knew and had observed and taken pictures to prove there was an area 51 and proof of what was going on there.
They then a few years back said it was shutdown or closed down but yet again people took the time to proove otherwise. They took bigger telescopes and bigger cameras and again climbed the tallest hills and mountains within the araea and again filmed and took pictures of activity going on.
Theres alot of info online about area 51 and its activities and secrets some retired employees have even fessed up and spoken out about what they new forsure was going on there and yet there was still things that were a secret and araeas restricted even to them. I was skeptic but after seeing pictures and hearing and seeing or reading articles / stories its there and certainly still in use. What really or actually is going on there we can only wonder and go on what people say that have been a part of it.
I would hate to live even remotely close to it thats all I know because them knuckleheads burn whatever they cant burry they burn along with all there leftover chemicals!!! Which the smoke alone caused death or nasty skin and health issues for for several workers from that facility. I believe in the mid 1990s President Clinton had listened to theworkers ho were affected by what was going on there and had signed things for their lawsuit.
This is scarry if even the Presidents dont realize whats happening there. Anyways Im sure as time goes on something will happen or somebody will slip up and all the truth will certainly come out. Until then the general public can only guess wonder and go on what others say and what their pictures reveal.
