Well shit, I read the Wikipedia link and some articles from the comment about the NOAA Hurricane Hunters and assumed you were referring to them.
The C-130J you linked from the ADS-B recorder seems to be military. Guess they’ve been using them for a while for storm reconnaissance.
Oh I didn’t know the Air Force Reserves did that! Though that makes a lot of sense given how it’s surveilling in proximity to the States. Good use of aircraft and brainpower in that pursuit.
