It's not that I think it. I have been told by your peers it occurs. I agree it's a crime, but it goes back to Diesel's statement of "what you know and what you can prove are two different things". What is silly is you and I both (and likely everyone here) knows that if you look hard enough, every aircraft in the universe could be grounded for something. It's not hard to do and to resort to something like this is weak.
As far as you not witnessing it, I believe that's entirely possible. If you scroll through my past comments, you'll see it that I believe there it's a small number of your group that creates problems. Every group regardless of industry has them. I'm speechless that nobody here has ever heard of such things.
