Did you see any markings? There are some large propeller driven Navy and Coast Guard weather/radar/search planes that do touch and go landings at Hilo and practice runs around the Big Island. Maybe it was one of them. I don't think the wacky-weed hunters routinely use large planes, so it probably wasn't Green Harvest.
