Refly BA038?
According to misd-again - "What the AAIB needs to do is refly the exact same scenario and do nothing. That will be the ultimate decider if the crew's actions increased, or decreased, the aircraft's performance."
How will that improve air safety? Whether the crew increased or decreased the aircraft's performance, what matters is that everyone survived without any life-threatening injuries. Seems pretty hard to improve on that result.
(And why are we discussing BA038 on this forum anyway?)
