President Abdul Kalam once disguised as Army man to fool CIA
To avoid detection by US spy satellites before Pokhran-II nuclear test, Indian scientists including then project lead Abdul Kalam used false IDs and dressed in Army uniforms as alibis. Bomb shafts were dug in the night while dug out sand were shaped like dunes. The five secretive detonations until May 13, 1998, were dubbed "CIA's biggest failure of the decade".
