Yes, I do. Do you know I worked for three years on critical flight controls 
systems at Boeing? I said so in the article(s). These ideas are not mine, I did 
not come up with them in 5 minutes at the keyboard. They're central to the 
aerospace design industry, and their fantastic safety record is testament to how 
effective they are.

May I draw your attention back to the "Dual Path" section.

Fly by wire failures are no different in principle from a total hydraulic system 
failure on a fully powered flight control system.

Airliners do suffer total hydraulic failures now and then, despite being unable 
to fly without hydraulics, yet land safely. I'll give you one guess how that is 
done :-) I can give you a brief rundown on how it works after you guess.
