Knowing your propensity to easily take offense, I tried to make it clear
that I wasn't questioning your credentials. I know who you are. I highly
respect your flying experience and the posts you make when RATIONALLY
discussing AVIATION matters. I don't want your certificate numbers.
Maybe someone else can answer my question.
