A group of pilots wrote a new chapter in the history of air warfare 17 years ago. In the Kargil War, they dropped laser-guided bombs on targets at an altitude of more than 17,400 feet above sea level. In doing so, they demolished the Pakistani post atop Tiger Hill, a post of extreme strategic value because it gave Pakistani gunners a perfect view of the town of Drass and National Highway 1A, the lifeline between Srinagar and Leh.
