I saw the footage of the fatal diving accident of Yuri Lipski. One thing I wonder is what really happened. He doesn’t seem to try to inflate his Buoyancy Control Device (BCD) to get back up.
Did he have a failure ?
Link to the video of his fatal dive, please be warned that this can be disturbing: Yuri Lipski’s Fatal Diving Accident Footage (YouTube).
(I read the comments below the video, they seem to be speculative. I was hoping that there was some source of information I am not aware of or a proper investigation).
