RedactedNarrative: Operator of V1 was returning after duck hunting on Felsenthal NWR, negotiating through the flooded timber with the sun in his eyes when a vine attached to a tree caught passenger 2 around his face and head causing him to be thrown into the operator.  This caused the operator to lose control of V1 and strike a tree.  Upon impact passenger 3 was thrown forward causing him to strike the side of V1 with enough force to rupture his spleen.  Passenger 3/victim was transported by EMS to the hospital where his spleen was removed.
