The duty of care in the GOM should be more clearly focussed upon the Oil Industry as they have the means to alter the balance. You would be correct that flying at night in a single outside the survival time without some mitigating safety equipment should be frowned upon if that were the case - my understanding is that singles at night in the GOM is the exception rather than the rule (and, as oil company policy changes, becoming more so). We might also wish to bring to their attention that flying in adverse weather in singles also increases substantially the risk as some accidents in the last two years have shown.
