Sorry for the off topic post but excrab…
CRM has been around for a very long time in various incarnations. It was only formalised in the late 1970s and with good reason.
I can only assume that your idea of having 2 crew being akin to having two engines is a tongue in cheek remark ? The difference between flying something on your own and doing it safely is blindingly obvious.
The reason for having 2 crew is not ” in case one of them dies “ and a 737 is not a citation or a king air and cant be flown as such.
