To put a bit of perspective on this, and avoiding the rights and wrongs. You run a commercial operation, you need an FO, you have a stack of CV's, many of which are suitable, one of the suitable CV's has a type rating of the correct type.
Do you employ the one with the correct type rating, or delay having the pilot online, and pay thousands for the type rating.
What would you do?
Obviously from the pilot's perspective, it's a rediculous risk, but many have taken it for both good and bad outcomes.
