It should be of no surprise to you that the FAA is described as a government agency that is; inefficient, incompetent, and loaded with mismanagement at all levels. Over-spending, low accountability, and corrupted officials that push for volume over safety.
Can we trust the the FAA to adequately implement NextGen in a safe manner, research environmental impacts, and equally distribute flight paths without singling out the same neighborhoods to take the brunt of the noise and air pollution? Doubtful.
Did you already forget about the falling piece of airplane equipment over Stewart Manor? Call that a lucky break, it landed on a resident’s lawn. Next time it could be your head.
