We're constantly being challenged to go way beyond what's currently there.
That's what makes some engineering really fun.
There's no better feeling than being able to solve the impossible.

For a 737, it's very hard to find areas to improve,
so a percent and a half is remarkable
especially just with the wing tip.
A winglet is a device used to help improve the aerodynamic
characteristic of the overall wing.
It makes the airplane more efficient.
The wing itself--it's got to carry the load no matter what
and it's just changing how the load gets carried.
The original addition of a winglet was on the order of
3.5 to 4% improvement, depending on the length of the mission,
and we're looking at improving that up to another 1.5% in fuel burn.
The change that the advanced technology wing really brings is
a radical departure from what we've done in the past.
It has features to it that you won't see anywhere else on any other airplane.
It's a differentiator.
It's kind of got this aggressive, yet eye-appealing nature to it.
It's the most obvious thing you're going to see with the MAX [737 MAX].
The airlines all over the world will save millions of gallons of fuel
with this concept.
Carbon emissions will be greatly reduced and the environmental impact
is going to be substantial because 737s fly multiple times a day.
[737 Flight Tracker] It's the most popular airplane out there.
As a person, it's a great feeling to know that we're impacting
and having a positive impact on the world.
