What is the purpose of D-Bag in skydiving parachute? And a few others popup to me. This is not about aviation (plane,glider etc). This is about sky diving. So should these be asked here or OP should look for another SE site? Or am I wrong?
I think there has been a discussion before on this topic (I can't find where, perhaps in chat) and IIRC the consensus was that skydiving is on-topic.
And it should be. Skydiving is a form of aviation.
