*Material uncertainties:*
– The precise duration in the air pocket is reported variously as “about 60 hours,” “62 hours,” “two days,” “two and a half days,” and “three days” across different sources; this article uses “more than 60 hours” or “approximately 60 to 62 hours” as the most defensible range
– The exact size of the air pocket is not established through direct measurement; “approximately four feet high” reflects reported descriptions
– CO2 and O2 levels in the air pocket were not directly measured; all estimates are from outside models
– The names of the eleven crew members who died are not available in the sources consulted
– Whether the Jascon-4 capsizing investigation produced formal safety recommendations is not established in available reporting
– Okene’s specific medical treatment for post-traumatic effects, if any, is not documented in available sources
– The exact cause of the capsizing remains “under investigation” per original reporting; no concluded investigation findings were found in the sources consulted
## The Architecture of Endurance
Survival psychology research consistently identifies a cluster of behaviors and mental states that distinguish people who survive prolonged life-threatening situations from those who do not. These are not exceptional traits present only in exceptional individuals; they are capacities that most people possess to some degree but that are activated, sustained, or exhausted under pressure in ways that determine outcomes.
