I flew for HUPL from 1968 to 1970 & then part time to 1974. It was a great company to work for & unlike some, they paid me every cent owed plus a bonus for being a good boy!
I think it was Don who was killed when he flew a 206 into the sea off Hayman or Heron Island when some idiots fired off some emergency flares at night. Don & the hotel manager both went to investigate & unfortunately were killed. If it wasn't Don, it was Dave, memory problems!
I believe Bryce put too many money into his cattle station & didn't have enough left over for HUPL. Both the ops in Indonesia & Fiji were sold off; I believe Don may have worked in Fiji for a while.
