It can't be other countries spying, right? Not with all the flashing lights/size of some of them?
I guess nothing can be ruled out after this barely there fed administration simply let Chinese balloons just canvass the country for awhile...
i think there are more "explained" than "unexplained" at this point.
Primarily if having red/green lights ( typical standard FAA id lights - depending on orientation can tell if heading/if traveling toward/away and altitude relative to viewer ) have been shown to be helicopters and planes.
But certainly others that dont have those lights or orientated in standard way that cant be explained.
Im of the thought, particular to NJ, we are seeing these very close to McGuire/Dix/Lakeland military base, so i think it could be combo of training exercises combined w/ drone use of different types.
A lot of the night videos dont give good depth perception- so something to the view that may seem relatively close by, could in fact, be 20-3 miles off.
