Summary
A diver recovery drill was aborted after uneven basket recovery strained and kinked a standby diver’s umbilical, restricting his main air supply and prompting bailout. Both divers reached the surface safely. The flash identifies communication, planning and supervision shortcomings, and emphasises umbilical management and incorporating incident learning into procedures.
