Oh Yeah, I've watched videos of that before. They are amazing.
I posted my little shots of the air traffic around my home, so people get an idea of what I have to deal with on a day to day basis. They are always flying into or out of a flight corridor near my house. I'm always getting those warning signals from my Remote. I wish they would go into the corridor at the ends, but they come into it or leave it from the sides, which gives them a flight path over my house. It's rare, but it happens. I've never had any close calls. With the RC warnings and my line of site I can easily avoid them.
