It is weird bro.
There were also recent reports of drones over Lakenheath RAF Base (airandspaceforces.com) in England.
If I had to guess, it would have something to do with the relatively recent transfer of Nukes (bbc.com) from the US to the UK, but the drones in NJ have been mostly over the Picatenny Arsenal in North Jersey, rather than McGuire AF base in South Jersey, where the nukes actually would've been flown from.
Like I said, I don't know what is going on, but it is all weird and barely talked about in the media, despite this happening for well over 6 weeks now.
barely talked about in the media,
That’s not their job to report things anymore.
I think the local media is only talking about it because people are calling it in all the time, and local politicians can't ignore it anymore.

But even then, they barely talk about what is actually happening.
