How to intervene?
How do you tell a fellow BASE jumper when to double check their actions? I’ve been thinking about this a lot lately. How do you tell someone that you know you are concerned about what they are doing without lecturing or pissing them off? Especially if they are more experienced than you in one particular facet of parachuting.
Do you nag? Do you threaten? Do you ignore them?
What techniques do you use to show the proper amount of concern?
