I don't agree that Bristow and CHC wouldn't cooperate with something like pilot training.
In the late 1970s, Bristow used to train pilots for the then British Airways Helicopters.
Since then, Bristow bought some Super Pumas and S76s from CHC when they were doing the Helikopter Service buy out. Both companies have a history of cooperating when they need to, especially if it reduces their costs.
In fact, since the CHC buy out of HS, there has been some other cooperation as well but I might get into trouble if I was to write about it here.
All is not what you see my friend.
