When I started this thread I wasn't sure what to expect; probably some yes, no or maybe so's... Instead it has turned into a great and fruitful conversation and thank you everyone, even Cardio! Anything new, or new to a person, often gets met with resistance, skepticism and misunderstanding. It's natural and generally a good thing; part of the vetting process. It would be interesting to put Orville and Wilbur in the cockpit of a modern jetliner or even a well equipped GA aircraft. I'm not sure if they would be full of amazement, wonder and approval, or their heads would explode!
