Nice one! My two favorite skydiving jokes are both short:
"If at first you don't succeed, skydiving's not for you."
And this one:
I read a story recently about a man who wanted to skydive, but he didn’t want to take the lessons. So, he just got himself a parachute and poked around until he discovered where the two cords were: the main ripcord and the emergency cord. He went up in an airplane, jumped out, pulled the ripcord—and nothing happened. He pulled the other cord, and nothing happened. As he was plummeting to earth, he met another guy coming up as fast as he was going down. As they passed one another, the man shouted, "Hey, buddy, do you know anything about parachutes?" And the other man responded, "No, do you know anything about gas barbeque grills?"
A blind man is telling his friends about how he's able to sky-dive.
"The parachute is packed and put on me," he explains."Then I'm positioned at the door, and the pilot tells me when to jump."
"But how do you know when you're gonna land?" asks one friend.
"Simple,"replies the blind man."The dog's leash goes slack."
