The man who found the wreck of the Titanic and the Bismarck is reported to be planning a trip to find Sir Ernest Shackleton's Endurance. Robert Ballard will sail a US Coast Guard ice breaker from Chile to the point were the ship was crushed in 1915.
Endurance is deep beneath the Antarctic ice pack.
Shackleton was attempting to cross Antarctica when he, his 26 crewmen and one stowaway were trapped but they made one of the greatest escapes in history. Dr Ballard is expected to arrive at the site in February and will use two remote controlled submarines to find and photograph the wreck. It is believed to be lying in 9,000 feet of water and the team may have to break through 20 feet of ice before they can even begin their search. The Antarctic is not a forgiving place. Shackleton's crew camped on the ice for five months before conditions were suitable for an escape.
