BASE jumping is an extreme sport. It is similar to skydiving, but there are important differences. Firstly, the jumps are much lower – usually no more than six hundred metres. And secondly, there is no aircraft. Instead, participants jump from some kind of bridge, building or cliff. The first BASE jump took place in 1912 in New York, when Frederick Law jumped for the Statue of Liberty. In the 1960s and 70s the sport became more popular, partly thanks to Carl Boenish. He made documentaries about BASE jumping and also 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.
