The Pacific Theater’s Most Daring Raid Guest: James M. Scott, author, "Target Tokyo: Jimmy Doolittle and the Raid That Avenged Pearl Harbor" Jimmy Doolittle's raid on Tokyo during WWII was one of the first turning points of the war. It was an act of vengeance for the attack on Peal Harbor and it shook the confidence of the Japanese. But what did it cost? The daring raid and the Japanese retaliation that followed. Operation Vengeance Guest: Dan Hampton, former US Air Force pilot and author, "Operation Vengeance: The Astonishing Aerial Ambush that Changed World War II" On April 18, 1943, a group of pilots embarked on a secret mission to take out Isoroku Yamamoto, the Japanese admiral who planned and executed the attack on Pearl Harbor. The actual “Operation Vengeance” is only the tip of the iceberg for this relatively obscure chapter in World War II.
