Long distance rescue
Most people have heard of the Titanic. It was the largest passenger ship in the world and was launched in 1912, but on its
very first voyage it hit an iceberg and sank in the Atlantic Ocean. Most of the 1,517 people on the ship died in the freezing
water. (1)
It is a very strange tale, but luckily it had a better ending than the story of the original Titanic.
Alex Evans works on a lifeboat in Wales and he spends a lot of his time rescuing people from the sea. They are usually
swimmers or fishermen who are stuck on rocks when the sea comes in. These rescues are usually simple and don't
require aeroplanes or international search-and-rescue operations. (2)
On Monday Alex was shopping with his mother when his mobile phone rang. He was surprised to get a signal and

calling their boats Titanic in the future!
A Then he contacted an international rescue centre.
B Mark was with some other men, taking a boat to Grenada.
C However, he doesn't have a boat himself.

D Luckily everyone was OK because of the actions of a good friend 4,000 miles away!
E They couldn't use the long-range radio.
F This week he was part of a sea rescue that was a little different!
G Imagine someone phoning you and saying that they are on the Titanic and it's sinking!
H Now another boat with the same name has been in the news because it got into trouble at sea.
