That's a great question. There's always is some communication that happens, certainly in our case before our first aircraft came, and we were quite collaborative with Boeing in that respect. However, you have to know what your expertise is, however, and we are not test pilots for aircraft certification; we are operators. There's a very different set of skill sets there and a very great difference of expertise. I think you have to be careful when you start to involve the operator too much in the initial certification of an aircraft.
Transport Canada, in its certification process, has test pilots, and they do certification work. In commercial aviation, however, we have a very significant delineation between pre-certification and post-entry into service. We are operators.
I said in my testimony at the beginning that I have conducted “customer delivery flights” and “customer test flights”, but that's post-production; it's from an operator's standpoint. I would caution that we want to keep the expertise in its lane. We're good at operating the airplane, but I certainly wouldn't have expertise in the certification, in many respects, of an aircraft.
