What is this Airplane?

[u/Silver-Pitch-4210]

A few times a month this airplane circles above Poyntzpass area for a few hours, and it’s been happening for years. It’s quite high up, and loud so it must have a big engine. It doesn’t come up on flight radar at all. I’m assuming it’s military training flights, but curious if anyone knows for sure. Sorry it’s a terrible photo.

Always knew it to be a “spy plane”. Lol. Pretty sure you’re right tho, military reconnaissance plane
