I agree with Sport on this one, Full scales have just as much responsibility as models to avoid a collision if they are aware that such a risk exists. That being said we all
know it's usually much easier for the model pilot to see the full scale than the other way around. Also I think we all know that we modelers should always do our very best
to fly safely and avoid full scale aircraft and IMO any model that is being operated in the landing pattern of full scale craft at high altitude is wrong and I think the FAA
should deal with such.
