That’s beauty of engineering, we’re not going to extend the length, add the same planform and decrease the range. So, the team, through understanding the performance of the -8, optimizing the configuration, they found a way to get the range and the extra payload.
I would say specific to the dash-9, as the dash-8 matures and nears certification, the dash-9 is a derivative off of that dash-8. So the more solid the dash-8 configuration is and becomes, the more straightforward the dash-9 derivative is. And that one is progressing very well.
