A Skydiving Lesson
All of these pilot and aviation jokes get me to thinking about my first skydiving instructor. During class he would always take the time to answer any of our stupid first-timer questions.
One guy asked, "If our chute doesn't open, and the reserve doesn't open, how long do we have until we hit the ground?"
Our jump master looked at him and in perfect deadpan and answered, "The rest of your life."
