I sent an email trying to give some support.
I did read how ever on another sea plane website that:
""In a five year study of the environmental effects of Seaplanes, the
U.S. Army Corps of Engineers concluded: Air Quality: no impact Water
Quality: no impact Soil Quality: no impact Wildlife: no impact
Fisheries: no impact Noise: similar to that created by a large
speedboat""
Perhaps if you could get a copy of the full report you will have some form of documentation to battle the ‘environmentalists’
It would also be good if we could get alot of support from fellow flyers.
