I have been flying my P3 4K for a bit now with an eye towards drones for use in SAR work.  Finally edited together a video for a demo. It has river flights, canine search work, rescue rope training, and general mountian scenery.  Thought I would share and hope you enjoy.

You're going to want the flir camera. Think litchi would be good for this to plot out a search grid, I can imagine having a small squadron to search large areas

It's really nice. Thanks for sharing.
