Boeing Adds Tiny Holes to Its Biggest Plane to Boost Efficiency
Boeing’s new 777X is getting a lot of attention for its composite wing with folding tips and its super-efficient engines, but one of the airliner’s most innovative features are the tiny holes in its tail that smooth airflow and improve fuel efficiency.

In Atlas Air's case, this would help you get to the wrong airport more efficiently. Similar to my golf swing, the more efficient dimpled golf ball that travels 10 yards farther simply means I have to go 10 yards farther into the woods to find it.
the same thing on golf balls, isn't it?
Reminds me of that old simpsons gag with "speed holes" in the car's hood.
Holes? Wow! A thousand more places for cracks and corrosion to start. Don't any Boeing guys golf? Dimples are not for looks on a golfball.
I am a bit surprised at the style of language used by the author of the article.
Either the author is lay man or the article was written for lay people.
Why and how ?
Hydraulics and aerodynamics
Hydrofoil and aerofoil
Laminar flow and turbulent flow .
These and some more words are the first few which every student of Fluid Mechanics learns !
So what is so big by wring that Boeing have been researching to achieve more and more laminar flow of air around tail ? In fact all aircraft manufactures endeavour to design EVERY aerofoil of an aircraft for perfect laminar flow of air around it. A cardinal principle and requirement ! Every other consideration comes second.
After all, what are the principles of creating aerofoil(or hydrofoil) sections ?
And how do you decide what is the OPTIMUM design ?
No way, to my humble mind. All is decided by the limits of the knowhow available at a given time, which in turn keeps improving.
At any rate, good going dear Boeing !

I drilled holes in my Columbia. Gonna save some fuel. Man, I'm green!!!
