those parts flying over stuff .. I still have problems proper guessing my glide angle with my 36km/h glideangle 9 paraglider.
I simply can't imagine how you figure out if you are going to make it 3m above some cliff approaching it with 160+ in a wingsuite with a pretty low glide...
@shresht123 I was using metric tonnes, 6,8t=6800kg. But even using american (907kg) or british tonnes (1016kg) you will get way to high values.
