Mary M. You said: "A few years back I was horrified when there were two midairs involving young people in Grob Tutor aircraft, due partly to an unqualified instructor flying with serious health problems, and also due to flying in crowded airspace when alternate areas were available."
Fact: the instructor was not 'unqualified', he was a Qualified Flying Instructor.
Remember that it was not only the Tutor that was flying in crowded airspace when other areas were available: so we're all the other aircraft; no one had to be there.
