This program is founded on the potential for achieving economies of scale. In other words, if a lot of users buy a large number of airplanes, we can drive the cost of this airplane down below what you're paying for a much less capable airplane today. That's really the only way you can achieve the costs we're talking about.
It's not that we found a magic way to make the airplane; it's that you have the economies of scale. In order for you to get the economies of scale, the airplane has to be viewed as affordable in the eyes of the buyers. That forces us to be focused on driving the cost of the airplane down to as low as it can be.
We're confident that if you look at it side by side with airplanes of today's generation, we'll be at or below the cost of those, and we'll have next-generation technology.
