Primary Failure Mode
As with all Recovery operations, the tangling of various lines (webbing, shroud lines, etc.) is a potential cause of failure.

In this scenario, prior to main parachute deployment, the webbing from the fin can wraps itself around and tangles with the webbing connecting the drogue parachute to the mission package. Three potential consequences of this failure mode are depicted and described below.
