No ... Competition is good.
Airlines generally have a choice of GE, P&W or R-R engines for their aircraft. This is a good thing, keeps all the engine manufacturers on their toes.
I want to see Vulcan succeed with the Blue Origin engine.
Is their engine uniquely different from the rptor?
I am not familiar with the differences
Yes - competition is good. But after a while everyone can settle on the best mousetrap, and not spend tons of money for minimal gain.
