Wrong.Wrong.Wrong.Wrong.Wrong.
Something tells me you got great relish posting that word.
So, anyway, like another poster pointed out, you don't really need to hear, to fly, what with all those instruments. And there aren't garbage trucks, emergency vehicles, school buses, etc. to worry about when flying.
I'm pointing out you're wrong in your assessment of deaf pilots or drivers. If you want to live in your ignorance and narrow little world, be my guest.
oh, btw, WRONG.
