I was sad to learn this morning that William Kershner died a few days ago. For those who don’t know, Kershner was a life-long pilot and flight instructor and is famous within aviation circles. When I was 8 or 9 years old, my dad was taking ground school and as part of that ground school, he had a text book called, A Student Pilot’s Flight Manual. The book was by William Kershner. Even at 8 or 9, I devoured that book, and I had it virtually memorized. I recall taking a practice written test in the back of the book and doing execeedingly well for a 9-year old. It was my first introduction to the fact that anyone who wanted to could learn to fly an airplane. Nearly 20 years later, I got my pilot’s license, and though I had other text books to work from, I would still pull out my old, tattered Student Pilot’s Flight Manual every now and then and study from that.
