Been doing some more research on Ian Gemmell. People might ask why the CP was sent down to the ice, but it looks as if Gemmell had been AirNZ's accident man for years. I note that an AirNZ DC8 crashed on take-off during a training flight in 1966, and that Gemmell was on the investigating team. So I can't see anything sinister in sending down the best man, even if he happens to be the CP.
