Seeking advice on crew management

[Robert Goodman]

I'm reading this with interest because let's say it does turn out that the cause of all these "blackouts" was indeed a concussion, or intracranial trauma that accompanied concussion. It shows that the return-to-activity protocols are unreliable. I've never been shown evidence for the protocol that's gotten wide acceptance now; seems it was just arrived at by committee out of nothing, just for the sake of having a standard answer to cover asses.
