My father was in the U.S. Air Force, and belonged to a skydiving club. He'd gone on dozens of jumps during his stint, and once or twice I remember overhearing him tell a friend, that he'd like to do one more.
Now, skydiving was never an activity I'd ever had a burning desire to undertake. But I figured if my dad wanted to emulate George W. Bush (who skydives to this day), I couldn't exactly let him go alone.
So, a few years ago, I jumped out of a perfectly good airplane with my 70-year-old father.
The thing that surprised me most was how quiet it is, as you're floating down to the ground. And the instructors and pilots at the school were incredibly respectful to my dad, regarding him as one of the pioneers who allowed the endeavor to become popular activity it is today.
