S1·E5 Prisoners of War

During an early morning strafing attack by Japanese Zeros Pappy manages to shoot one down. After taking the pilot prisoner they begin to discover it's hard to hate him. He has lived in the U.S. and speaks perfect English and begins to warm up to the Squadron. But what Pappy really wants to know is what the sonar device was doing in his plane and what his mission has to do with the Japanese task force which is on the move.
