I think our schedule, as it is right now, is based on a regulatory environment that adopts standards. Right now, Transport Canada, for example, doesn't have appropriate regulations for these and borrows them from other groups. There are the airship design standards from the FAA and there's also a standard in Europe with EASA. These are probably going to be the full basis for the vehicle, because a vehicle that will be globally operated will need to have one or both of those. But to operate it as a Canadian operator in Canada, we have assumed that Transport Canada will adopt regulations consistent with and appropriate to a new vehicle, in other words will not use balloon regulations or things like that.
