VH-ANB at Darwin as well, where they went to flight idle and simulated a simultaneous failure of the engine
and autofeather system. Which itself was almost a carbon copy of the B1900
incident at Williamtown only a couple of years earlier...
EDIT: I hadn't seen the ATSB animation from the -ANB crash. It's available for download
HERE. Doesn't take long for things to go awry...
