A case does not make a general truth.

Please considere the bandwidth of a 747 filled with dual layer DVD-R (or
now blu-ray).
It will blast even your fiber, on raw value of provided bandwidth.
Yet, the plane won't leave before it get full... may take a few hours of
latency to cover the 100 miles (most on ground).

Bandwidth and latency are not always connected. In fact, for a real
situation, a satellite link (dedicated, you have $$$) is really a big
bandwidth, yet the latency is uncompressible, and worse than a fiber to
make a 100 miles trip.
