This has been happening for a solid five years now. When I used to work the night shift I'd go out for a smoke and see one of these things pretty far up in the sky almost every day. Not sure what the sudden concern is about.
Northern New Jersey is just a seemingly endless suburban sprawl, and one of the most affluent regions in the country. There are a lot of labor aristocrats with back yards and disposable income to spend on toys like this. I assume if they were being used as part of some clandestine operations, they wouldn't have bright fucking red and green navigation lights on them.
If anything, these things are part of some federal program, not some foreign intelligence operation.
if anyone can find any video footage of these I'd be interested because all I can find is indistinguishable from a normal-ass plane.
