1st Lt. Rex T. Barber engaged the first of the two Japanese bombers, which turned out to be Yamamoto's plane. He sprayed the plane with gunfire until it began to spew smoke from its left engine. Barber turned away to attack the other bomber as Yamamoto's plane crashed into the jungle. Afterwards, another pilot, Capt Thomas George Lanphier, Jr., claimed he had shot down the lead bomber, which led to a decades-old controversy until a team inspected the crash site to determine direction of the bullet impacts. Most historians now credit Barber with the claim.
