Why did you tell me?m, I wanted to figure this out=!!
How long did it take you to figure out?

I have a few ideas, and if wrong a few questions =80
Other ideas:
1.
=ven though you dismissed weight, I wonder if there is something about the =eight that alters the optimal
fuel burn ration during takeoff when thrust =s highest that hinders range down line?
2.
=oes the pain alter the high lift devices such that takeoff and landing are=less fuel efficient?
Observations:
1.
='ve never seen a commercial jet painted black... I wonder if=the problem is the color or the
application/variant you used=/p>
2.
=upersonic jets (no need for Bernoulli) are black all the time (though this=may have more to do with anti-
radar) and/or they may be willing to give up=range in exchange for these
3.
= was trying to do a Gedankenexperiment <http://www.merriam-
webster.com/dictionary/g=dankenexperiment> to simplify the problem: imagine two fast cars, identical in every=way,
except one is pained black. Would the same range-reduction effect be =bserved? If not, would it be because cars are
dominated by rolling resistance and form drag, while subsonic pla=es are dominated by skin friction? Or would the
effect be absent because t=e speeds are too low?
Lastly, a question:
When you "undid" this black paint th=ng, did you strip off the black paint, or did you just re-paint? If the la=ter,
did you recoup the lost range?
