i've done it.
i took 2 hr training prior to jump,,basically it was abt,how to chck whether the chute opened properly or not,,,whether ur fall speed is ok or not,,if not how to open extra chute in diff. circumstances,,,how to change directions,,how to land witout injuring urself.
it was a grt experience.
gud luck
For beginners a static line is used. I've done one a few years ago and you just jump out of the door, the rip cord is attached to the plane and pulls as you exit. From there on, enjoy the ride.
