Michael,
You had to have put that there yourself because that was never committed
to CVS (I know...I wrote it). It works, but it's a major hack and
shouldn't be in the official FG source (IMHO).
Someone needs to rewrite the viewer code to allow viewpoints to be added
at runtime; then, we can define a tower position for specific airports
and allow you to switch to the nearest tower. And as usual, I don't
have the time (much less the programming prowess) to take on such a
task.
