The time to talk about corrective actions is when the cause is known.
A lot of folks were talking about engine failures, non-containments, and what's wrong with engines in general. then they started talking about flaps and slats and when they couldn't agree on whether they were deployed or not they start talking about reversers and even though there is no agreement on whether they are deployed or not some are already proposing corrective actions without any comparative data.
I will say it again everything that man designs or builds will break, some more often than others. For crying out loud how do you fix something that hasn't broke? You're just liable to screw it up even worse.
Let's get back to arguing about what's broke before we try to fix it and that goes for crew error suppositions as well.
I used to have a big sign on my office door
"all ye who enter bring data"
Then we could decide how to fix it
