Skydiving AFF 1 gone bad: student loses both instructors, flips upside down and spins out of control

AFF 1 student has a tumbling exit from the plane. One instructor releases. Other instructor forced to let go. Student upside down and spinning. Scissor kicks did not help the recovery effort. Kudos to instructors for quickly resolving the issue and releasing the chute at 6500 feet. The rest of the jump goes well.
