A side note about Parachutes and their harnesses. My local rigger once told me to get into a strict regimen of always buckling and un-buckling in a specific order. His story was that people have survived a landing in trees, only to hang themselves when unbuckling the leg straps before the chest strap when trying to extricate themselves from the trees. Whether or not that's an apocryphal story or not, it does make sense to build that muscle memory so the steps are automatic when it counts. On my chute (a National 425), I can see obvious problems if I release the leg straps first. There does appear to be some risk of falling through the chest strap and (at minimum) getting a nasty jerk on the chin.
