I've had a minor involvement in this and lobbied for the inclusion of the 47, but the Producer maintains this is not a history lesson for purists, it's aimed at a wide general audience. Big is good, phwoar-factor and heli-porn are the driving forces. The Robinsons are in there to represent the second helicopter revolution, affordability. As to when it will air, they've only just started shooting and it's not scheduled yet.
