The painting shows three steel towers with their
transmitter antennas slung between. On the lower left, the "girl on the
tube" interprets the "blips" of enemy aircraft on the screen. The
information was then sent via the telephone (lower right) to filter and
operations rooms where the table-map could be updated by a "plotter"
(top right). The markers represented hostile and friendly aircraft and were used
to plan and monitor air battles. 234 Squadron’s Spitfires (top left) peel
of to intercept enemy bombers. The succession of functions became commonly known
as "Read", "Report", "Filter", "Identify",
"Tell"
and "Plot". Select the painting for an enlarged view. |
