Here is another local group using a drone for good
DJI ? - really ? :D
flying "stright line"
"up to 80k/h" - torpedoing any other aerial vehicle in it's way ? - there's no way for it to detect a baloon/ultralight/helicopter, etc. collision with a bird, and hurting people below..
standing by with fully charged li-po = poor battery life/performance when you need it.
We'd all like to see this in the future, but we need an anti-collision system that "everyone" is using first, before this can become a viable idea. >Right now, it's just another "pizza delivery" dream.
Its a fantastic Idea... However i don't think this would work in extreme weather conditions.
