APPLE on a Bullock Cart. This image has become a symbol of Indian innovative thinking. The story behind this is that APPLE was to be tested for Telemetry, Tracking, and Command link. It required an antenna test to be conducted in an open field. Since the instruments were very sensitive, they required a non-magnetic environment. Doing the test outside India would have cost them time and money. The solution was thus found in five hours and an Ox cart was hired for 150 rupees, and tests were conducted without further delay.
