The Warbird Discovery of the Year 2004 label, for the first time, is given to two aircraft instead of one. The aircraft though two in number, have the same lineage and almost similar history. They are the IAF Kanpur 1 at Chandigarh and the IAF Kanpur II with IIT Kanpur.
Both aircraft have been designed by late Air Vice Marshal Arjan Singh - and both carried an IAF serial number.
