you're not using a client that supports colored tables and have tried
to compensate. Low graphics mode looks much better on clients that
do... we recommend switching to Netscape 3.0 or Microsoft Internet
Explorer.

Effects of Earth's Curvature
on estimating a target's position
One must account for the curvature of the earth when determining the
altitude of a target. Distant targets, which are close to the ground,
cannot be seen by a radar because they will be below the horizon.
The height of a distant target that is above the horizon will be
underestimated if the curvature
of the earth is not taken into account.
