Why is May 11 observed as the National Technology Day?
May 11 is marked as National Technology Day to commemorate India's technological achievements, including Operation Shakti at Indian Army's Pokhran Range in 1998. After five successful nuclear tests, Ex-PM Atal Bihari Vajpayee declared India a nuclear state, the sixth country to do so. On the same day, India successfully tested its first indigenous aircraft Hansa-3 and short-range missile Trishul.
