Suppose to be closed but some how they manage to keep it open, If is no main control or whatever is then why the spraying of chemtrail for the last 18 years over the City's.
The problem was they create the cloud first and using it like umbrella for military communication, the issue is after they use it and no longer need everything coming down we breathe it all that plants as well will be affected, do you ask yourself why people feels tired and hill, some will said well is just the pollen or dust every year same problem, same problem yeah right.
If is nothing going on then what exactly they doing with all that ?.
