Another interesting thing to see will be the public reaction, when a first loco crashes (God forbid). And the reaction of the Irishman.
Whilst I detest the vile Irishman who runs RYR, I don't think the first LoCo to stoof in will have a harp on its tail. The finished product of their training department is every bit as good as or better than European legacy carriers. Where they really stink as a company is not in flying but in other areas.
