The first thing to consider when thinking of sky diving is the safety of the company providing the sky diving. Extensive research should be done on any sky diving company before actually sky diving.

AFF stands for accelerated free fall. AFF is one sky diving training method. If you choose AFF as your sky diving training method, you can be cleared sooner for solo sky diving than if you choose other sky diving training methods.

Sky diving

You would say

"We went sky diving last Sunday"

"Did you just hear that Susan went Sky Diving?"

"James jumped out of the airplane without hesitation and it was the greatest example of sky diving I have ever seen"

Other sky sports besides skydiving are sky surfing, sky dancing, free falling, and paragliding. Some of these start the same as sky diving, jumping from a plane!
