Gabilian, would that C210 you mention happen to be KWW?
Said aircraft grinded its belly landing at HID- think I heard QF one day on Centre discussing it when they were inbound to Horn.
Word is that its common practice to pull gear CBs in the survey 210s; pump motor interfering with equipment or something. And it was subsequently forgotten.............
I recall a mate telling me it was doing East-West runs somewhere around Weipa up and down the Cape.
