Figure 4.1. The
FlightPanel_1
class displays the flight path of an unexploded shell.
Aerial shells are designed to explode high in the sky, with spectacular results. But
occasionally, a shell does not explode at all; it is a
dud
. If a shell does not explode, its return
to Earth becomes interesting. A shell, unlike a rocket, is unpowered, so if you ignore the
effects of wind and air resistance, the flight path of a dud is a simple parabola. Figure 4.2
shows

the
window
that
appears
when
you
execute
Flight-Panel_1.main()
.
