Ahh... humour. Argh, argh, argh...
We already have "Birdmen" who use a variety of techniques to reduce the risk of bird/aircraft collisions at most major airports. Seriously. It's a 24/7 job, probably pays pretty well and they drive cool trucks.
Drones and manned aircraft already share the same airspace- obviously with the military but also when considering low-level civil aircraft, be they piston-powered Cessnas or unpowered gliders.
Commercial aircraft have a system called TCAS to reduce the risk of collision. Some elements of that 30-year-old technology could easily be updated and incorporated into today's drones. As a pilot- I'd love to see a transponder-equipped drone on my NAV display. Maybe it won't take evasive action, but if I have 3 or more miles warning-
I can.
We're talking about systems that would make the sky safer and more useable for
all of us. Why wouldn't you want that? With the photography that I like to do- I'd love to take my drone up to 5 or 6,000 feet. I'd be willing to pay for a transponder or subject myself to licensing and testing if these things allowed for great utilization of my Phantom.
