I was there from 1970 and even was seconded to Bechtel working
in the Cinema centre in Melbourne.
My Department employed 120 people, the average age was 19, I was the old man at 32: 5 Expats average age 22, the rest Bougainvilleans and other Papua New Guineans hired straight out of mostly Mission Schools.
One of the lab techs became a Professor in Chemistry and Minister of Minerals and Energy, Samson Akoitai, unfortunately he died last month.
They were the best crew I ever had, smart kids.
