Admiral Yamamoto's aircraft wreck is the area's most historically interesting wreck. Admiral Isoroku Yamamoto, who planned the attack on Pearl Harbour, left Rabaul in a 'Betty Bomber' on 18 April 1943 with a protective group of Zeros, not realising that US fighters were waiting for him near Buin. The wreckage of the bomber still lies in the jungle a few kilometres off the Panguna-Buin road. It's signposted, near Aku, 24km before Buin.
