Ducks and Geese can fly well over 1000ft. They do this in Migration periods.
We are not talking Ducks and Geese here, that's Nature, can't change that. We are facing the problem with unknowing individuals that buy a Drone, fly recklessly, endanger full scale Aircraft near Airports. Some of them don't know the rules of Flight Safety, and the others that do, without regard to the rules. That is the problem. Will this kind of behaviour among those people, give us Law abiding Members of the RC Industry more Restrictions? I believe it will if it continues. I hope not, but when the First Full Scale Aircraft is directly involved with it's flight path from a Remote Controlled Aircraft or Drone, crash or not, we shall see big problems in the future.
