Definitely not POM. Coastal ports served by the F-28 in those days were WWK, MAG, MAS, KVG, RAB, KIE and LAC. The only crushed coral strips (or environs) back then were MAS and KVG. Apart from BNE and CNS (of which it is neither), HIR was the only other international port served by the F-28, but I don't recall the F-27 going there, hence my confusion.
