In working with hardened surfaces I see two things that appear to be an annomally.
First
When landing on an elevated hardened surface the shadow shows at the elevation of the hardened surface not ground level.
Second
Even when the hardened surface is concrete you see dust blow up from it.
Are both these just something that we must live with or is there a way to not have dust and shadows show on elevated hardened surfaces?
