Helping United Help Itself

So I have this fantastic idea that should really help save the airlines some money: I suggest that well above 18,000 feet they retract the little landing lights from the wings. This 737's tired flap track cowling was just shaking like the dickens! I feel "See and be Seen" is one thing, but really, at what price?

Then Phil turned me onto this little nugget for those with more dollars than sense!
