If we were to have 4 cylinders (only one of which would be in use any given
day), such that the cylinder's edge was more or less down the centerline of
the runway (one on each side); or perpendicular to the runway (one at each
end), then, other than altitude, the spectator appeal is about the same as
with a line.

(We ought to change the subject of this thread.)
