well pimpjoe i'm skeert of hights too (beliefe it or not and i'm a pilot) the thing is it's not like standing on a mountain or on a tall house or something.. when you look out of the plane at 14000feet your eyes are not made for depth perception THAT far and it's kindda like looking onto a blanket or a film .. there's no feeling of "fark that's far away"
go out to the next dropzone and make a tandem! even if you don't want to skydive yourselfe afterwards it's a most memorable exerience
