CHALLENGE- skydiving

The most challenge I want to do is Skydiving.  I want to feel flying in the sky like a bird and enjoy the. 
Skydiving means freedom, you can see the whole city under your eyes.  
SKYDIVING- is the action sport of exiting an aircraft and returning to Earth with the aid of gravity, then slowing down during the last part of the descent by using a parachute.

Skydiving is a sport involving a skydiver jumping down from an airplane while it is flying and parachuting to the ground. Skydiving can be done individually and with other people. Training is required to go solo. The jump can also be made from a helicopter or the bottom of a hot air balloon from 4000m or 13,000 ft. Some thrill seekers attempt to skydive without a parachute whilst flying through the air, and instead rely on the small parachutes they have that professionals have put on them.
