Weird Flight radar symbol

[Keepingthingsinteresting]

Does anyone hav any idea what the weird symbol north of Shrewton represents? I will attach a photo.
Presumably a drone but no info available and not seen it before.

It’s a drone. There’s an article on FR Support explaining the different categories of symbols used and there’s a picture of that icon there.

I don't know what that is, but there's currently hot air balloons above Hawaii and north and south of Florida.
