Who person jump in the buildings?

Although your question isn't very clear I think you want to know about BASE jumping. This is an activity where a person using a parachute jumps from tall non moving objects. The name says just that:

Building

Antena

Span(bridges)

Earth(mountains)

People have been doing this since the parachute was invented almost three hundred years ago. It is a very dangerous thing to do which makes it illegal in almost all of the world. Many people have died. Nowadays, some consider it to be an extreme sport like bungee jumping and there are competitions because the safety has improved and also the people who do this are professionals who trained for many years before attempting the jump.
