A family who have spent over 10 years searching for a missing plane in the Canterbury High Country are seeking help from mountaineers to get into the alpine terrain. In 1962 a dragonfly plane took off on a scenic flight from Christchurch to Milford Sound with five people onboard, including a newlywed couple. Despite one of the most extensive aerial searches in New Zealand history, the plane has never been found. Sally Murphy reports has this report.
