Zf275. 02a. the speakers. 201215 75th Anniv. Oryoku Maru,Bob Hudson 24a. Professor Rico Jose was the main speaker. Bob Hudson and Jack Walker told me several times how impressed they were with his knowledge of the Hellships. One fact they learned that 4 are sunk in Philippine Waters. I know the professor personal; we explored the tunnels under Fort Bonifacio together. And I know he is very famous, I watch the News!
