Natasha Flacon Brian, a French woman based in Australia who worked for Sundance, a consultant and a British citizen and the British pilot were also on board. Trading in Sundance shares was halted and chief financial officer Peter Canterbury was named acting chief executive. "This is a deeply distressing time for the families of the missing, their friends and work colleagues," Canterbury said. Reports said Talbot, a truck driver's son, first made his fortune through a network of pubs before founding mining company Macarthur Coal. He left Macarthur over corruption charges and was due to go on trial in August. Company chairman Wedlock was an ex-head of BHP Billiton's iron ore division, while Flacon Brian was an executive with Talbott's resources investment company, Talbott Group.
