That's not that far, I've had buddies jump higher shit than that. That's high (50-60ft) but doable. Not pleasant though... These dumbasses totally hit the water wrong.
their is no way that person died from the impact due to the water, do the math catalyzt, i would say that was 15m and 15*9.8=150m/s and thats not even enough to kill someone...maybe knock him out if he landed head first which he didn't ...and for someone to die from inertia, first he has to land completely flat on his belly or back which they didn't and they have to be at much higher speed ..so they died or not from the water and one more thing people who keep saying water is hard i show u the math from so called physics so u can stop saying shit cuz the speed is nothing close to kill somone
