During the operations against Pakistan in December, 1971, Flight Lieutenant Kalyan Brata Bagchi was serving as an Interception Director in the Eastern Sector. On the 22nd November, 1971, Flight Lieutenant Bagchi observed on his radar scope one single blot close to Jessore heading towards our border. He scrambled four Gnats from Dum Dum within half a minute. He positioned his fighters with precision and achieved such a tactical advantage that the moment the Pakistani Air Force intruders entered the Indian territory at Boyra, our fighters were ready to engage them. Flight Lieutenant Bagchi continued to give direction to pilots and this resulted in shooting down of three Pakistani Air Force Sabre Jets and capture of two pilots. In this action, Flight Lieutenant Kalyan Brata Bagchi displayed professional skill and devotion to duty.
