How do skydivers hit their marks?

It would also impact the design of umbrellas.

I made my first jump in 1982; my student training was static line. I eventually got a jump master rating and took a lot of people up for their first jump. Threw a few WDIs in the process! I’ve had some off-airport landings also. More than once I’ve caught rides from nice people who saw me coming down. Never ran into an irate farmer but I’ve been to drop zones that warned me “Whatever you do, do not land in this field!” while showing me an aerial photo of the DZ.
