BASE jumping is an extreme sport. It is (1) similar to sky-diving, but there are important differences. Firstly, the jumps are much lower – usually no more than 600 metres. And secondly, there is no aircraft. (2) Instead, participants jump from some kind of bridge, building or cliff. The first BASE jump took (3) place in 1912 in New York when Frederick Law jumped from the Statue of Liberty. In the 1960s and 70s, the sport became more popular, partly (4) thanks to film-maker Carl Boenish. He made documentaries about BASE jumping and also (5) thought of the name. He died in 1984 while he was jumping in Norway. BASE jumping is a thrilling experience but it is very risky too.
