If I could go back in time the first place I’d go would be back to the 1880’s and talk to Geronimo. I’d tell him “About 20 years from now two bicycle makers from North Carolina will create a machine that will be able to fly thru the air under it’s own power. These machines will improve over the decades to the point where people will be able to fly anywhere in the world. Then some people will train and practice jumping out of these machines while they are flying through the air.
Sometimes they jump out because the flying machine has became unsafe. Other times they will jump out to attack their enemies on the ground by surprise. Most of the time, however, they’ll jump out of the machines miles in the air just for the sport of it. They think it’s fun. And here’s the best part, Geronimo – just before they jump out they call out your name!” I bet he’d find that interesting.
