Task: Question Answering
Input (English): Passage: In 1940, a replacement, Pilot Officer T. B. "Septic" Baird, is landing his Hawker Hurricane at "Pimpernel" Squadron's airfield. Just as he touches down, however, a straggler from an earlier mission taxis across his path. Septic's quick reactions allow him to "leapfrog" the other Hurricane, averting a costly disaster. His action, however, causes him to crash his replacement aircraft into the bungalow of Squadron Leader Barry Clinton at the end of the runway.
This earns Septic the wrath of his new squadron leader, Bill Ponsford, because he damaged his fighter aircraft. The crash also injures the ligaments in Septic's neck, which he is able to self-diagnose, as he had been a medical student before the war. The next morning, Septic is told by Group Captain "Tiger" Small that he will not be able to fly until his neck is healed, so he will instead serve in the operations room for the time being.
Several days later, with the risk of a bombing attack on the airfield, and all of Pimpernel Squadron's Hurricanes scrambled, Tiger orders all aircraft to take off and fly out of harm's way until the raid is over. With Tiger quickly assembling all available pilots and finding aircraft to fly, Septic wins a foot race with Small to claim the last spare Hurricane for himself. He then proceeds to shoot down a Messerschmitt Bf 110 from the attacking force. His delight is short lived however when he is admonished by Small and Sqn Ldr Peter Moon for leaving his radio set to transmit, preventing the returning Hurricanes from being diverted to an undamaged airfield. A crestfallen Septic returns to his ground duties. 
Question: What is the nickname of the person that the squadron leader angry with after his fighter aircraft is damaged?
Output (English): Septic.
