Andy LeonardA 5-day cross-country road trip showed how quickly good planning fades once it starts working. Gas planning is the same life skill: set limits before pressure exists, protect the margin, brief every dive, and build the capacity to notice drift.
Lanny Vogel Learning From Emergent Outcomes (LFEO) moves diving investigation beyond blame. Detailed analysis using the PETTEOT framework allows diving accident learning to go beyond the obvious cause to improving systems and procedures.
Gareth LockTelling divers to 'just speak up' misses why they stay quiet. Speaking carries an immediate social cost; silence pays later. Power isn't rank, it's how much you have to lose. Those who see the problem most clearly often have the least room to say so.
Andrzej GornickiAt the very moment when we should give up, the signs are faint. If everything were already falling apart, the decision would be easy. The problem is that the right decision to give up should be made when nothing has happened yet...
Human factors, non-technical skills and learning from emergent outcomes for the divers who refuse the bad-apple story.
