I too have the Honiara 'tick' including the flyby of the WW2 wrecks. I think I posted a pic of some of them earlier but here is a repeat below. More than one rusting Landing Ship was being used to house chickens.
It was on either Honiara or one of the other small islands that we were refused fuel as they had not been paid by FEAF for the last Herc visit. Our vision of an idyllic enforced stay was shattered when FEAF woke up and wired the money down. We left on schedule the next day.
