Summary
A winch wire trapped during preparation to launch an air-diving recovery system parted, dropping a 300 kg clump weight near a saturation diving bell and deployed divers. No injury or equipment damage occurred. The flash identifies missing pre-use checks, restricted drum visibility and loose-wrap design issues, recommending checks, visibility and drop-zone identification.
