This test was initiated from 1500' over water. The parachute is a Raven 4 measuring 282 square feet with an all up weight of 125kg. I used a fairly standard BASE packing method similar to what Supair shows in their video. Round type shackles should connect to the risers, never use standard carabiners. Investigations have shown that it's possible for the second ring to bind in the biner and prevent detachment. Make 100% certain that the small link from the deployment bridle is attached to the hole in the shackle screw. This could easily be overlooked. Do not attach the bridle directly to the shackle as this could cause the second ring to bind when releasing.
