They had a whole heap of turnbacks because of HF failure. There is only one HF radio in their aircraft, which is not the way to run oceanic operations with any reliability. One Captain was severely criticized (and it may have contributed to his being laid off, even though they are now advertising for pilots) for his stance on turning back on Honiara and Norfolk flights whenever the HF died. It was expected that pilots could bluff their way there and back home by using VHF to ask other aircraft to relay. That may be OK very occasionally, but when it becomes a habit ATC and everyone else who uses the HF system gets a bit pissed off.
