I've never had a hostile confrontation on any of my flights, but I have had curious questions:
A. Do you see what it sees on the screen?
Yes. I also see info on battery levels, altitude, speed, and other flight data
B. Could you see: me INSIDE my house; outside of my house; what I was doing; etc.
INSIDE your house? No. The rest? Perhaps, if I was looking for you, which I wasn't. People (generally) ruin my shots/video.
C. How much did that 'thing' cost?
Enough. (I give the total cost of everything they can see - all the batteries, the backpack, spare props, etc.)
D. Do you have to licensed to fly here/wherever?
No, I don't have to be licensed. There is a FAA Remote Pilot license which I am 'studying' for. Regardless, there are FAA guidelines which I have to follow, licensed or not.
E. Do you have permission to fly here?
I'm sorry, I wasn't aware I need permission. This is public property/land. Where or to whom do I direct a question for permission? (If on private land, this doesn't happen...because it's private land...)
That's pretty much the gist of my 'questioning' by a curious public. And with regard to 'B,' I find it remarkable how quickly some people will make a situation 'about them.'
