Hi Chuck.
I don't waste the effort in PPRuNe style 'debates'. The facts speak for themseleves old mate and a little research and historical study goes a long way.
I am not here to eductae anyone but I do take the time to bring info to the attention of my colleagues who may be interested.
Don't listen to me, listen to the worlds foremost authorities and consider what is prudent in that light.
Cheers,
Brad
