This was a horrible accident. With all the emphasis on the type of harness used we should not lose sight of the fact that based on what they believe to be known, this was not the cause of this accident. The preliminary cause is that something yanked the lever. This could still have been the case with any kind of harness you use. How do you avoid that in ships where that potential exists. That can obviously happen with a regular doors on flight if loose objects are moved. A less than perfect autorotation is not that uncommon when the circumstances are a real emergency so the quick release is critical but successful egress is still required and that may depend on where you are flying and what you have to land on when the lever is snagged.
