In the news section I spotted an item about a Norwegian Navy vessel heading to the Barents Sea where they will scour an area of the seabed in search of the missing seaplane of polar legend Roald Amundsen. The Norwegian explorer, the first person to navigate the Northwest Passage and the first to reach the South Pole, disappeared in 1928 while trying to rescue Umberto Nobile, an Italian who had flown to the pole in the airship Italia and crash landed on the ice on the way back.
Despite having fallen out with Nobile after a 1926 flight over the pole, two years later Amundsen offered to go and look for him. On June 18 1928 at around 4.00 PM, he took off with a crew of six in a state of the art twin-engine Latham 47. Three hours later the plane transmitted what were to be its final signals. Nobile and his crew were rescued on June 22.
Last August, a team led by New Zealand explorer Rob McCallum returned from a two week search for the aircraft empty handed. Lots of useful information can be found at Search For Amundsen.
