The MiG-27, which proved to be an "ace attacker" during the 1999 Kargil War, roared through the skies for one-last-time on Friday after serving the IAF for over three-decades. The swing-wing fighter has been the backbone of ground-attack fleet of the Air Force for several decades and the IAF will bid adieu to its squadron of seven aircraft from Jodhpur Air Base, officials said.
