Think you may be right, they could have full possession of one EC145 now - although that doesn't mean they've made it operational yet.
My evidence? Well, you pointed out that they are still registered to McAlpine, but you didn't note that MPSB was this week marked up as "Potential change of Registered Ownership in progress" by the CAA, and this is the one that will be delivered first. MPSA is the "trials horse" and will be delivered last.
So, what of the high-time 355Ns? Any truth in the report that they will acquire VON# registrations...?
