The examples (other than chloroform in grass) were well inside his area
of training. He holds an A&P Certificate. It's FAA test material. The
stuff he goofs up on is the stuff that he's teaching A&P students. You
want your airplane repaired by someone who narrowly squeaked by his
exams with a 70% score?

And the Navy didn't do any better with him.

So, just like A&P Master Instructors, and their students, and their
students on down the line, the Ph.D.s among us may be every bit as good
as those they learned from.
