Very cool and sad, you probably have his P-38's last photo.
Lt. Colonel Bob "Westy" Westbrook scored seven kills while flying a P-40F with the 44th FS, 18th FG. After switching to the P-38 he scored another 13 kills with both the 44th FS and the 347th FG where he held the position of Deputy CO. Westy was Killed in Action on 22 November 1944. At the time of his death his score was 20 confirmed kills and two probables. Lt. Col. Westbrook was the sixth highest scoring P-38 ace. He was awarded the Distinguished Service Cross, two Silver Stars, two Distinguished Flying Crosses and 16 Air Medals.
On November 22, 1944, Westbrook was leading the flight to destroy the Japanese naval convoys in Makassar bay. The flight proceeded to destroy or heavily damage 13 vessels by strafing. While strafing a Japanese gunboat, Westbrook's P-38 was hit by anti-aircraft fire from the convoy. He leveled his P-38 in an attempt to make a water landing, but the P-38 turned its nose down and slammed into the water, killing him instantly. His wingman was also shot down in the same mission, but was rescued by an U.S. Navy PBY Catalina. Westbrook's remains were never recovered.
