The results of an internet search by the grieving mother of a MIG-21 pilot killed in a 2001 crash forced the IAF to finally admit that the young officer was not responsible for his own death.Four years—and endless letters, emails and phone calls—after Flt Lt Abhijeet Gadgil died in a fiery crash, Kavita Gadgil (54) just got some kind of closure in the form of an apology from Air Chief Marshal S P Tyagi.Until now, the IAF said it shared Gadgil’s anguish but implied that a lack of flying skills claimed the life of Lt Gadgil in Rajasthan on September 17, 2001. Worse, on behalf of the IAF, Air Marshal Ashok Goel wrote to Gadgil in March 2003, accusing her of carrying a ‘‘public tirade’’ which would ‘‘demoralise the force and would not be in the best interest of the nation’’. But on March 23 this year—five days after an Air Marshal was flown to Mumbai from air headquarters in Delhi to apologise—Air Chief Marshal S P Tyagi finally acknowledged in a letter to Gadgil that her son’s crash ‘‘may have been triggered by a trim malfunction’’. Tyagi also said the IAF was expunging Goel’s letter from its records. In the end, the door Gadgil was looking for came from an internet search on spatial disorientation: it put her in touch with an IAF doctor on the panel of the crash inquiry.
