As ZQA commented
Too early to speculate what happened, or why it happened, but when BWIA was closed, many of the more experienced pilots were picked up by sandpit operators. The pilots union was squeezed out, and a new philosophy was put in place. Let us say it was slanted to "productivity".
They say that a safety culture dies slowly unless nurtured carefully.
It has been 5 years since the old regime was broken up, I hope the replacement will stand scrutiny in the investigation.
I do hope they can stand an audit. Most of the trainers and fleet managers from the old BWIA along with more than half the line pilots plus the same with the ex Air Jamaica pilots who were merged had to find new homes, mainly in the UAE, UK, US and India.
