BUT who’s drone is it??

Some quick googling:

The drone is owned by a Brian Emfinger of NW Arkansas. He lists himself as a storm chaser.

How did you find that out??? How big is the drone?

Very interesting. His other vids have anywhere from a few hundred to a few thousand hits. This one (AR tornado) has over 1.7M hits!
