I myself have never done it before and will not do it. It's too risky for me. Skip the plane just a bit you do wrong then your place is a grave and many military members who have ended there.
Not only the height and greatness of the plane we should see, but the wind direction and all its changes must also be considered. Parachutes are the most important thing for many people who are killed because when they are above the parachute they will not open and flourish. Coupled with landers who do not necessarily run with much fluent wrong and christmas due to an improper landing. For me personally it is too dangerous .
Thanks.
