At least 16 people have died after a small plane crashed just after take-off in French Polynesia. The pilot and 19 passengers were on board at the time and the chances of finding any of the four still missing look bleak. One local fisherman said that he and his colleagues did all they could but that nobody survived. The twin-engine plane was leaving the Pacific island of Moorea bound for Tahiti. The routine journey usually lasts less than seven minutes. Among the victims were two European Union officials. Most of those on board were French nationals. There were also two Australian tourists. The cause of the crash is unknown. The French government has sent a team of investigators to draw up a technical report.
