Guess it has to do with whichever dictionary one uses: Kind of whether one wants to look for and make things better or as Able, just keep the blinders on.

Perhaps I should have used "intangible". Maybe on to "incorporeal" however that's a function of law.
I don't apologize for using a term that sent you to the dictionary, Able. Good preparation for your next lesson.

I still say that AMA offers the REAL model aviators, those willing to help make a future for the sport, many things that are there yet one cannot hear, see, smell, taste or touch them. It's up to those that want better to assure that better will happen.

BTW, Able, why did the basic question give you a "....bad attitude moment."
