Sure does. Of course, the same negotiation for the use of the runway
also occurs successfully every day at thousands of uncontrolled
airports throughout the world. Kind of makes you question the
necessity for a tower at Renton at all, doesn't it?

Not that the FAA is the ultimate source of wisdom, but when they say a
facility is not busy enough to need a tower, they are usually right.
What NFCT really means is this - we're not busy enough to actually
need a tower, but we want to pretend like we're a big airport and have
one anyway.
