[AussieO2]

I recently read somewhere of a report that one O-2 ditched on the delivery flight to Vietnam. They flew in a group of 5 (Ducklings) with a C-130 (Mother Duck). Fitted with long range tanks and extra oil tanks in the cabin. One had a problem with the rear engine and had to ditch, pilot was picked up by a Japanese freighter ship and taken through to Japan. (Later returned). Reports suggest oil tank over filled during routine airborne transfer and foaming occurred. Can anybody provide more info about this or any delivery flights of O-2's to Vietnam?
