Little St James is flyable from the main island with the Mavic Pro 2 Zoom he is piloting which might explain the shortness of the videos. He gets within 6-8ft of that window and the dude immediately grabs his radio to notify everyone. The crazy thing is that 2-3 people walk by right under it as he is making that call. Dude might want to be a bit more careful with his $1250 drone.
I have not looked into it, but I do not see why you couldn’t. You are live-streaming to yourself at 720p as you fly, so you should be able to hand that feed off to something else. I know I can do a Wifi/screen mirroring trick that passes the feed to an AppleTV so people can watch inside.
