If the jumper_intends_ to cut away his main parachute(and that is
fun!), then they are required to wear a third parachute per FAA
regulations. The container/harness system is modified or built with "D"
rings on the front to accept the third deployment system. Tom

A number of people I know have bought used parachutes. The first thing they

That's a good thing - careful inspection. Even better that they take
more than one parachute. Do you know if they take only 2? Is it even
possible to take 3?

And crazy looks like a pretty fair description of people that jump
from perfectly good airplanes.
