Thomas George Lanphier Jr. was a Panama-born American colonel and fighter pilot during World War II who was first given sole credit, then later partial credit shared with Rex T. Barber, for shooting down the plane carrying Admiral Isoroku Yamamoto, the commander in chief of the Imperial Japanese Navy. Most modern historians discount his version entirely, giving Barber the whole credit for the kill.

Colonel Rex T. Barber was a World War II fighter pilot from the United States. He is best known as a member of the top secret mission to intercept the aircraft carrying Japanese Admiral Isoroku Yamamoto in April 1943.
