Cute, but that section begins with how it's important to avoid flying through a thunderstorm. The tips on flying through one begin with this phrase: "If you cannot avoid penetrating a thunderstorm, the following are some Do's Before entering the storm:". Emphasis located right in the text. I'm pretty sure "I'm a doctor with a Bonanza and need to make it to my meeting" does not count as "cannot avoid penetrating a thunderstorm".
